THE MANGO.
This magnificent fruit, which is practically unknown outside of the tropics, has become as hardy as a forest tree throughout our eastern seaboard, wherever it is planted out of frost. It has been named, and well named too, the apple of Queensland, as it stands as much neglect, and can be grown with as little care and attention as, or even less, than that given to the apple-trees in many of the Somerset or Devonshire orchards. It will not, however, stand frost. Droughts and floods have little effect on it; it will grow in any soil, from a sand to a heavy loam, amongst rocks, or on a gravelly or shaley land. Naturally, it does best in good land, but there are hundreds of cases where trees are doing well and bearing heavily on land that is by no means fruit land. The mango is one of our handsomest fruit trees; the symmetry of its growth, its large glossy leaves, the delicate colouring of its young growth, which is of different shades in different varieties, the abundance of fruit that it produces, varying in colour from dull-green to yellow, red, or even purplish tints, all render it conspicuous. As well as being one of our handsomest, it is also one of our most widely distributed fruits, being found growing luxuriantly the whole length of our eastern seaboard. A few trees are also to be met with inland in districts that are free from frosts, so that it stands both the dry heat of the interior and the humid heat of the coast. As a tropical fruit it naturally reaches its greatest perfection under our most tropical conditions, the trees there growing practically wild, requiring little if any attention, making a rapid growth, coming into bearing early, and producing heavy crops of fruit. Further south the growth is somewhat slower, though the trees grow to a large size and bear heavily. It is one of the easiest of trees to grow, as it is readily propagated by means of seed. In many plantations thousands of young seedlings may often be seen growing under the old trees, the seeds having taken root without even having been planted. In most cases it is propagated from seed, the stones of fruit showing especial merit being planted either in a nursery, or, better, still, where the tree is to remain permanently, as it usually does better when so planted than when grown in a nursery and thence transplanted to its permanent location. The land should be well worked prior to planting, and the young trees require to be kept free from weeds and undergrowth till such time as they occupy the whole of the ground, when they are able to look after themselves, and require no further attention, at any rate in the warmer parts. It is not at all uncommon to come across a mango-tree, in full bearing, in vigorous health, that is growing wild, the result of a stone that has been thrown away by someone who has eaten the fruit. The young tree has not only been able to hold its own against all kinds of indigenous growths, but has developed into a vigorous, healthy tree, thus showing that it is perfectly at home, and that the soil and climate of Queensland suit it to perfection. The fact that by far the greater portion of our mango-trees have been grown from seed has resulted in the production of innumerable varieties, many of which are of decidedly inferior quality, as one never knows when planting the seed what the resultant fruit is going to be like. One is more likely to get good fruit by planting the seeds from selected fruit of the highest quality, but is by no means certain to do so, as a number of seeds always revert to inferior types.
This has had a bad effect on our mango industry, and has been apt to give the fruit as a cla.s.s a bad name, so much so that we find it difficult to get our Southern neighbours to take to it at all readily. I can quite understand anyone, whose first experience of a mango is that of an inferior fruit, full of fibre, and having a distinctly disagreeable flavour, condemning the particular fruit, but because there are inferior fruits one should not condemn the whole without knowing what a really good mango is like.
[Ill.u.s.tration: Mango Trees, Port Douglas.]
We have many good mangoes in Queensland, but only a few that are really first-cla.s.s, and of the latter I have yet to meet the man or woman, who is a fruit-eater, who does not appreciate their exquisite flavour, and who does not consider them worthy to rank with any of the finest fruits.
By many a really fine mango is considered to be the king of fruits, and I am not at all certain that they are not right, but, at the same time, a really bad mango is indescribably bad.
The mango grows to a large size here, even when comparatively young. I know trees over 50 feet in height, having a spread of the branches of more than 60 feet, a main trunk nearly 3 feet in diameter, that are under thirty years old, and that have borne from 1 to 2 tons of fruit for a single crop. Hundreds of tons of fruit go to waste annually for want of a market, or are consumed by farm animals, as the consumption of the fruit is practically confined to this State, and the production is greater than we can consume, despite the fact that mangoes are in season from the end of September to March, and that they are a favourite fruit with all who have acquired a liking for them. In addition to the consumption of the fruit in its fresh state, a quant.i.ty is converted into chutney, but this is so small that it has no appreciable effect on the crop as a whole. The unripe fruit makes an excellent subst.i.tute for apples, and is used stewed or for pies or tarts, and when sliced and dried it may be stored and used in a similar manner to dried apples.
[Ill.u.s.tration: Mango Tree near Brisbane.]
In addition to its value as a fruit, the mango forms a handsome ornamental tree, and one that provides a good shade for stock. It is very free from disease, as with the exception of one or two species of scale insects, which do not cause any very serious damage, it has few serious pests. It is a fruit that is bound sooner or later to come into more general favour, particularly when the qualities of the finer varieties are better known. Until quite recently it was considered to be one of the most difficult trees to propagate by means of grafting or budding, hence its propagation has been practically confined to raising it from seed, but now we have found out how to work it by means of plate-budding, and are able to perpetuate our best sorts true to kind.
This is sure to lead to a general improvement of our existing varieties, as old trees can be worked over by this means, or young trees of approved kinds can be grown in a nursery and distributed.
The fruit is very wholesome, is much appreciated by all who have acquired a taste for it, can be used fresh or dry, ripe or unripe, and cans well. It is a great addition to our list of purely tropical fruits, and finds a place in all orchards or gardens where it is capable of being grown.
THE MANGOSTEEN.
Many attempts have been made during past years to introduce this delicious fruit into Queensland, but these always resulted in failure.
True, a certain variety of mangosteen has been successfully grown at Port Douglas, also on the Lower Burdekin, and rumours of the existence of the true Java mangosteen (_Garcinia mangostana_) have been received, but, in nearly every case, they have, on investigation, proved to be _Garcinia xanthochymus_, or some other species. At the Kamerunga State Nursery, however, trees of undoubted parentage were successfully raised.
It is said that a thriving young plant, which is unquestionably _G. mangostana_, is owned by Mr. Banfield, of Dunk Island. The records of the Kamerunga Nursery show that in October, 1891, a quant.i.ty--about 100--of ripe mangosteen fruit was received from the Batavian agency by the then manager, Mr. Ebenezer Cowley, from which some 600 seeds were obtained. Of these, only a few germinated. The next mention is of the distribution, in February, 1892, of six plants to an applicant on the Mossman, and of two more in May of that year. Since then several young trees have been raised at the nursery, and one of them, in January, 1913, fruited for the first time for twenty-two years, and is the first to have done so in this State. Some of the fruit was sent to the Department of Agriculture and Stock, and proved to be fully equal to those of Java. A full history of the mangosteen and of its introduction into Queensland is given in "The Queensland Agricultural Journal"
(vol. x.x.x., June and July, 1913). The photographs were taken from the original fruit.

THE PAPAW.
Continuing our list of tropical fruits, we now come to the papaw, one of our most wholesome and useful fruits. It is grown all along our eastern seaboard in situations that are free from frost. It comes into bearing early, and is a heavy cropper. Like the other tropical fruits already described, it does best in our warmer parts, coming to maturity earlier, and producing better fruit. In many of the Northern coastal scrubs it is often met with growing wild, and producing fruit in abundance, the seeds from which the trees have been produced having been dropped by birds or distributed by other natural agencies. The papaw fruit resembles a rock melon somewhat in shape and flavour, the fruit being produced in the axil of the leaves all along the main stem, where they are cl.u.s.tered thickly together. The tree does best on well-drained soils, and is very sensitive to the presence of clay or stagnant water at the roots, hence it usually does best on scrub land or land well supplied with humus. It is propagated entirely from seed, which grows readily in such soils, and under favourable conditions will bear its first fruit when about ten to twelve months old, and continue to bear for three or four years or even longer. When the trees becomes old, however, the fruit decreases in size and deteriorates in quality, so that it is necessary to plant a number yearly in order to keep up a regular supply. It is a very handsome tree, with large spreading leaves on long stems, beneath which is its cl.u.s.ter of fruit--as many as 100 fruits being sometimes found in different stages of development on the one plant. The fruit ranges in size from 2 lb. to some 6 lb. in weight, and when ripe it is of a greenish-yellow or sometimes orange colour. The flesh is yellow, and when quite ripe it is moderately juicy, and of a flavour that it not always appreciated at first, but which one soon becomes very partial to. It more nearly resembles the flavour of a rock melon than that of any other fruit, and the seeds, which are found cl.u.s.tered in the centre of the fruit, have a flavour that closely resembles that of seeds of the nasturtium. Both the seeds and the fruit contain an active principle called papain, which is really a vegetable pepsin, that has the effect of greatly a.s.sisting in the a.s.similation of all food with which it is eaten, hence it is a valuable remedy in the case of dyspepsia, and persons who take the fruit regularly are never subject to this exceedingly troublesome disease. The fruit can be used both as a vegetable and as a fruit, the former in its green state, when it is boiled and served with melted b.u.t.ter, resembles a vegetable marrow or squash, but is superior to either of these vegetables. As a fruit it is either used by itself, or in conjunction with other fruits it forms the basis of a fruit salad. It is largely used in the North, and its cultivation is steadily spreading South, as its valuable properties are becoming better known. Its cultivation is very simple. The seeds are either planted where the tree is to remain, or are raised in a bed and transplanted to their permanent position in the orchard when strong enough to stand shifting, care being taken to select a dull moist day. The young plants are protected from the sun for a few days till they have become established, after which all that is necessary is to keep down weeds and to work the soil round them, taking care not to injure the roots. A good mulch of decomposed vegetable matter round the plants is an advantage, but they are usually so easily grown that little extra care is given to them. The papaw bears male and female flowers, which may be on the same trees, but are usually on different trees, so that it is usual to speak of male and female trees. This is, however, a mistake, as according to Bailey the plant is polygamous--that is to say, male, female, or hermaphrodite flowers may be found on the same or on distinct plants. The male flowers are usually on long scantily-branched auxiliary panicles, whereas the female flowers are mostly in the axils of the leaves close to the stem. The two trees are not distinguishable from each other till they come into flower, hence it is advisable to set the young plants fairly close together--say, 6 feet apart--and thin out the male trees when same can be distinguished by their blossoms.
Besides its use as a fruit and vegetable, the papaw makes a fair conserve and an excellent sauce, and its medicinal principle, "papain,"
is an article of commerce.

THE COCOA-NUT.
Although this palm can be grown for ornamental purposes as far south as Brisbane, its cultivation on commercial lines will be confined to the coast district north of Townsville, and to the islands off the coast, as, in order to develop its fruit to perfection, it requires a tropical climate. Where the climate is suitable it does well, it makes a rapid growth, and bears heavy crops of nuts. Old palms on the beach at Cairns compare favourably with any growing in the South Seas, and I am of opinion that its culture in commercial quant.i.ties on suitable land will be found profitable. The cocoa-nut palm does best right on or adjacent to the seash.o.r.e, in comparatively poor sandy soil--soil that is usually of little value for general crops, though it will grow mangoes well. So far, it is not grown in any large numbers, and although there is a ready sale for the ripe nuts, there is no attempt to make copra or to utilise the coir. Copra is the dried flesh of the nut, from which oil is extracted, and is largely used in the manufacture of soap, candles, &c., the refuse left after the oil has been extracted being used for cattle feed. Coir is the fibre surrounding the nut, and is used for the manufacture of matting, door mats, &c.
There is a considerable area of land suitable to the culture of this fruit on our Northern coast, which is at present lying idle, that, in my opinion, can be turned to a profitable use by planting it in cocoa-nuts as, in addition to utilising land otherwise of little value, we would be building up a new industry. The trees come into bearing in about eight years after planting the seed, and will continue to produce crops for many years without any attention. Care will have to be given for the first few years, whilst the plants are small, to keep down undergrowth and to prevent fires from running through the plantation, but, once fairly established, the plants will look after themselves. A cocoa-nut plantation gives a distinctly tropical look to the district in which it is grown, and the palms, particularly when young, are very ornamental; when old the long bare stems detract somewhat from the beauty of the top. It is a palm that I believe has a good future before it in the North, and for that reason I have included it amongst our tropical fruits, though it is cultivated at present more as an ornamental plant than as an article of commerce.

THE GRANADILLA.
A vine, belonging to the natural order Pa.s.sifloreae, that produces one of our most delicious tropical fruits. The papaw and the pa.s.sion fruit belong to this same order. It can be grown all along our eastern seaboard, but comes to greatest perfection in the North. The fruit is of a pale greenish-yellow colour, cylindrical in shape, and varies in weight from about 1 to 5 lb., the largest fruits being produced on a sub-species. The fruit consists of an outer pulpy covering, which can be used for cooking if desired, which surrounds a cavity filled with seeds which are encased in a jelly-like ma.s.s. This is the portion eaten, and to use an Americanism, "It is not at all hard to take." It is either eaten by itself, or is used in conjunction with papaw and other fruits to make a fruit salad, a dish that is fit for the food of the G.o.ds, and once taken is never forgotten.
The granadilla is easily grown from seed, and the plants are trained on an overhead trellis, the fruit hanging down on the underside. It is a heavy bearer, and once planted requires little attention. It requires a free, warm soil, that is fairly rich, to be grown to perfection, hence it is most commonly grown on scrub land. It can, however, be grown on any well-prepared land of a free nature. Unfortunately, it is a difficult fruit to ship any distance, hence its consumption is mainly confined to the districts in which it is grown, and where, needless to say, it is greatly appreciated. It is in fruit more or less all the year round, its main crop being in early spring in the North, and during the summer months further South. It is sometimes made into jam or jelly, but when preserved loses much of its characteristic flavour.

THE Pa.s.sION FRUIT.
This fruit is very closely related to the granadilla, but is much hardier than it, and can be grown to perfection much further South. It is not injured by frost to any extent in any part of coastal Queensland, and can be grown a considerable distance inland. It is more rightly a semi-tropical than a tropical fruit, though, as it is so nearly related to the granadilla, I have included it amongst the tropical fruits. It is also a vine, and, when grown commercially, is trained along a horizontal trellis, in a somewhat similar manner to a grape vine. It is readily grown from seed, and will produce fruit in less than twelve months from the time that it is planted, and will continue to bear fruit for some years. It does best on a free, warm soil of fair quality, though it may be grown anywhere with care, and often thrives well in very poor soils with the addition of manure. It is found growing wild on the borders of many of our scrubs and elsewhere, the seeds having been deposited by birds or other agencies, and under such conditions it produces an abundance of fruit. The fruit is of a roundish oval shape, and is of a dark-purple colour. It is about the size of a large hen"s egg, the outer skin being hard and sh.e.l.l-like, and the centre filled with the seeds, which are surrounded with a jelly-like ma.s.s and a yellowish pulp. It is a very fine flavoured fruit, and is universally liked. It is grown in considerable quant.i.ties in the Southern part of the State, and is one of our commonest fruits. It has usually two crops a year--a summer and a winter crop--but can be got to produce its fruit at any particular time that is desired by systematic pruning at different times of the year. It is often grown over sheds, dead trees, fallen logs, &c., which it covers with a ma.s.s of dense green foliage, and converts what would otherwise be an unsightly object into an ornament. The ill.u.s.tration herewith shows this well, and gives a good idea of the growth of a single vine.
Commercially it is grown on trellis, so that the land between the rows can be kept well cultivated, and also to permit of ease in the gathering of the fruit. When ripe, the fruit drops, and the gathering is usually from the ground. The fruit carries well, but will not keep for any length of time, as it shrivels up. It is princ.i.p.ally used as a fresh fruit, though it is also made into jam or jelly, and it often forms part of a fruit salad, taking the place of the granadilla. It has few pests, and is one of the easiest fruits to grow.

CUSTARD APPLES.
Under this heading I will include all the Anonas, such as the sour sop, sweet sop, bullock"s heart, and cherimoya. The sour sop is purely tropical, and is very sensitive to frost, but the other species are by no means so tender, and can be grown anywhere along the coast where the soil is suitable, as well as at many inland places. All the species produce very fine fruits, that vary somewhat in shape, in the roughness of the skin, and in size. The sour sop is the largest, and attains a size of 6 to 8 lb. The fruit is covered with soft spines, and is of an irregular oval, or even pyriform, shape. It ripens very soon after it is gathered, consequently cannot be sent any distance. It is a pleasant fruit of an aromatic sub-acid flavour. The pulp surrounding the seeds is of a woolly consistency, and this is surrounded by a custard-like ma.s.s which is much appreciated by those who have acquired a liking for it. It is a comparatively uncommon fruit, and is confined to the tropics.
The sweet sop is the commonest of the Anonas, and is grown throughout a considerable part of coastal Queensland. It is usually of an irregular roundish shape, very full of seeds, which are surrounded by a custard-like pulp of very pleasant flavour. It is usually a heavy bearer, and is the variety most commonly met with in our fruit stores.
The tree is hardy and is easily grown.
The bullock"s heart is a stronger-growing variety than the previous one, the fruit is larger, and, as its name implies, heart-shaped. It is also fairly seedy, the pulp of a light-brown colour, and more gritty, and not, in my opinion, of first-rate quality. It is most commonly grown in the North, where it is a very hardy and prolific tree.
The cherimoya is the best of the custard apples. The tree is a strong grower, with large handsome leaves, but, as a rule, it is not a very heavy bearer. There are many varieties, the fruit of which varies considerably in size and shape, and the skin is sometimes smooth and sometimes warted, or even covered with short soft spines. It has usually comparatively few seeds, and these are surrounded by a rich custard-like pulp, which in the better kinds is of very fine flavour, and is generally much liked. The fruit is not a good keeper, still, given careful handling and packing, it can be kept for nearly a week.
All custard apples are easily raised from seed, but the better varieties are propagated by grafting strong seedlings with wood taken from a tree producing fruit of especial merit. Any good fruit soil will grow them, and they do not require any especial treatment.
