s a stick three by four inches in size. The braces,four in number, and each secured by a four-inch spike, are twelvefeet in length, four inches wide, and two inches thick. An inchboard is driven at the foot of each brace. Thus the signal is madepermanent. Unless they excite the cupidity of the surroundinginhabitants, they will stand a long time. The black and whitecambric flags used are six feet long. At each of these points afive-inch flower pot is buried about eighteen inches below the sur-face, and a thorough description of the exact triangulated point ismade, from holes drilled in adjacent rocks or boulders, or fromsuitable objects which give promise of permanence. For theunderground mark I recommend a suitably-inscribed piece of vitri-fied earthen ware. For use in buoying, I recommend that the signals be boardedup and whitewashed. We thus have a cheap but probably success-ful sextant point. I ask that you recommend such legislation aswill cause these signals to be duly respected.

1882.) engineers report. 89 The signal at Tucks Island is erected on solid rock. It is asomewhat difficult place to erect a signal. The braces are sixteenfeet long, the other dimensions being four by six inches. The survey was made in two sections. The part from BlackBoy point to Sachems Head was made first. As we did not havean instrument suitable for connecting with the coast-survey trian-gulation, it was necessary to measure a base line, and also to obtainour own meridian line. The base line is 11,559.81 feet in length.It was carefully measured with a steel tape, which was held on thetops of short steel pins. A plumb line was used when necessary.About 9,000 feet of this line is on a salt marsh. The elevation ofthe end points is perhaps thirty and eighty feet. For the meridianline we made an observation on the north star. On the other sec-tion we were fortunate in finding two of the coast and geodeticsurvey points. This gave us a direct connection. I respectfullycall your attention
