"Is this Senator Rickrose?" the Lieutenant inquired.
"No," said Macloud. "Senator Rickrose isn"t coming until later. I am one of his friends, Colin Macloud, and this is Mr. Croyden and Mr.
Axtell."
"Very glad to meet you, gentlemen!" said the Lieutenant. "The Superintendent presents his compliments and desires to place himself and the Academy at your disposal." (He was instructed to add, that Captain Boswick would pay his respects to-morrow, having been called to Washington to-day by an unexpected wire, but the absence of the Chairman of the Naval Affairs Committee rendered it unnecessary.)
"Thank Captain Boswick, for Senator Rickrose and us, and tell him we appreciate his kindness exceedingly," Macloud answered. "We"re camping here for a week or so, to try sleeping in the open, under sea air.
We"re not likely to prove troublesome!" he added.
Then they took several drinks, and the aide departed.
"So far, we"re making delightful progress," said Croyden; "but there are breakers ahead when Hook-nose and his partner get in the game.
Suppose we inspect the premises and see if they have been here in our absence."
They went first to the place where they had seen them conceal the tools--these were gone; proof that the thieves had paid a second visit to the Point. But, search as they might, no evidence of work was disclosed.
"What does it mean?" said Croyden. "Have they abandoned the quest?"
"Not very likely," replied Macloud, "with half a million at stake. They probably are seeking information; when they have it, we shall see them back again."
"Suppose they bring four or five others to help them?"
"They won"t--never fear!--they"re not sharing the treasure with any one else. Rather, they will knife each other for it. Honor among thieves is like the Phoenix--it doesn"t exist."
"If the knifing business were to occur before the finding, it would help some!" laughed Croyden. "Meantime, I"m going to look at the ruins of the light-house. I discovered in an almanac I found in the hotel last night, that the original light-house was erected on Greenberry Point in 1818. This fact may help us a lot."
They went out to the extreme edge, and stood gazing across the shoals toward the ruins.
"What do you make the distance from the land?" Croyden asked.
"About one hundred yards--but it"s very difficult to estimate over water. It may be two hundred for all I can tell."
"It is exactly three hundred and twenty-two feet from the Point to the near side of the ruins," said Croyden.
"Why not three hundred and twenty-two and a half feet!" scoffed Macloud.
"I measured it this morning while you were dawdling over your breakfast," answered Croyden.
"Hitched a line to the land and waded out, I suppose."
"Not exactly; I measured it on the Government map of the Harbor. It gives the distance as three hundred and twenty-two feet, in plain figures."
"I said you had a great head!" Macloud exclaimed. "Now, what"s the rest of the figures--or haven"t you worked it out?"
Croyden drew out a paper. "The calculation is of value only on the a.s.sumption--which, however, is altogether reasonable--that the light-house, when erected, stood on the tip of the Point. It is now three hundred and twenty-two feet in water. Therefore, dividing ninety-two--the number of years since erection--into three hundred and twenty-two, gives the average yearly encroachment of the Bay as three and a half feet. Parmenter buried the casket in 1720, just a hundred and ninety years ago; so, multiplying a hundred and ninety by three and a half feet gives six hundred and sixty-five feet. In other words, the Point, in 1720, projected six hundred and sixty-five feet further out in the Bay than it does to-day."
"Then, with the point moved in six hundred and sixty-five feet Parmenter"s beeches should be only eighty-five feet from the sh.o.r.e line, instead of seven hundred and fifty!" Macloud reflected.
"Just so!" said Croyden.
"But where are the beeches?" asked Axtell.
"Disappeared!" Croyden replied. "As the Point from year to year slipped into the Bay, the fierce gales, which sweep up the Chesapeake, gradually ate into the timber. It is seventy years, at least, since Parmenter"s beeches went down."
"Why shouldn"t the Duvals have noticed the encroachment of the Bay, and made a note of it on the letter?" Macloud asked.
"Probably, because it was so gradual they did not observe it. They, likely, came to Annapolis only occasionally, and Greenberry Point seemed unchanged--always the same narrow stretch of sand, with large trees to landward."
Macloud nodded. "I reckon that"s reasonable."
"Next let us measure back eighty-five feet," said Croyden, producing a tape-line.... "There! this is where the beech tree should stand. But where were the other trees, and where did the two lines drawn from them intersect?"...
"Yes, now you have it!" said Macloud--"where were the trees, and where did the lines intersect? I reckon you"re stumped."
"Let us try some more a.s.suming. You had a compa.s.s yesterday, still got it?"
Macloud drew it out and tossed it over.
"I took the trouble to make a number of diagrams last night, and they disclosed a peculiar thing. With the location of the first tree fixed, it matters little where the others were, in determining the direction of the treasure. It is practically the same. The _objective point_ will change as you change the position of the trees, but the _direction_ will vary scarcely at all. It is self-evident, of course, to those who understand such things, but it was a valuable find for me. Now, if we are correct in our a.s.sumption, thus far, the treasure is buried----"
He opened the compa.s.s, and having brought North under the needle, ran his eye North-by-North-east. A queer look pa.s.sed over his face, then he glanced at Macloud and smiled.
"The treasure is buried," he repeated--"the treasure is buried--_out in the Bay_."
Macloud laughed!
"Looks as if wading would be a bit difficult," he said dryly.
Croyden produced the tape-line again, and they measured to the low bluff at the water"s edge.
"Two hundred and eighty-two feet to here," he said, "and Parmenter buried the treasure at three hundred and thirty feet--therefore, it"s forty-eight feet out in the Bay."
"Then your supposition is that, since Parmenter"s time, the Bay has not only encroached on the Point, but also has eaten in on the sides."
"It would seem so."
"It"s hard to dig in water," Macloud remarked. "It"s apt to fill in the hole, you know."
"Don"t be sarcastic," Croyden retorted. "I"m not responsible for the Bay, nor the Point, nor Parmenter, nor anything else connected with the fool quest, please remember."
"Except the present measurements and the theory on which they"re based," Macloud replied. "And as the former seem to be accurate, and the latter more than reasonable, we"d best act on them."
"At least, I am satisfied that the treasure lies either in the Bay, or close on sh.o.r.e; if so, we have relieved ourselves from digging up the entire Point."
"You have given us a mighty plausible start," said Macloud.
"Land or water?" Croyden laughed. "h.e.l.lo, whom have we here?" as a buggy emerged from among the timber, circled around, and halted before the tents.
