(9) SPIRIT LEVELING IN NEW YORK, 1896-1905 AND 1912-1916. E. B.. M arshall,. Chief Geographer.. IN T R O D U C T IO N .. Cooperation.—The State o f New Y o rk contributed financially to the work during the years 1896 to 1905 and from 1912 to 1916, in clusive, being represented by the office o f the State engineer and surveyor. Previous publication.—The follow ing results o f s p irit leveling are supplemental to and accord w ith the elevations contained in B ulletin 514, and are in agreement w ith the 1912 adjustment of precise level ing. Descriptions and elevations o f bench marks in B ulle tin 281 are reprinted in this volume w ith corrections and additions. B ulletin 514 and this bulletin together contain practically a ll re sults o f leveling in New Y ork State by the United States Geo logical Survey, the Coast and Geodetic Survey, the U. S. Lake Sur vey, the New Y ork State Survey, the Board of Deep Waterways, and by the Corps of Engineers, United States A rm y. These eleva tions are like ly to be changed but little by any future adjustment. Corrections.—The follow ing corrections to B ulletin 514 should be noted: Pages 13-17, Lyon Mountain and Dannemora quadrangles: Connection made in 1912 w ith Coast and Geodetic Survey bench m ark at Plattsburg necessitated a readjustment of elevations, and the corrected results are published in this volume. Pages 17-18, Massena and Potsdam quadrangles: As a result o f additional connections, circuits were readjusted in November, 1916, and corrected eleva tions are published in this volume.

Page 125, Risby Lakes should be “ Bisby Lakes.”. Personnel.—The field work from 1896 to 1906, inclusive, was clone under the direction o f H. M. Wilson, geographer, and the later work under F ra n k Sutton, geographer. The work since January, 1908, was done under the general direction of R. B. Marshall, chief geog rapher. Credit is given in the headings o f the several lists to the respective levelmen. The office work in preparation of lists was done m ainly by S. S. Gannett, geographer, under the general direction o f E. M. Douglas, geographer. Classification.—The elevations are classified as precise or prim ary, according to the methods employed in their determination. The form er are determined by lines o f levels run either in both forward and backward directions or by simultaneous double-rodded lines, a high-grade instrument being used and special precautions being taken in observations and reduction to correct errors and make the line continuously good throughout. The latter or prim ary levels are determined w ith the Y level, the levels being run mostly in circuits o f single lines. The allowable lim it o f error observed on the precise work already done by the Geological Survey in this State is repre sented in feet by 0.03 -/D and tha t for the prim ary work by 0.05 fiD , in which D is the length o f circuit in miles. Bench marks.— The standard bench marks are in two forms. The first form is a circular bronze or aluminum tablet ( C and E, PI. I ) , 3J inches in diameter and $ inch thick, having a 3-inch stem, which is cemented in a d r ill hole in solid rock in the w all of some public building, a bridge abutment, or other substantial masonry structure. The second form (F , PI. I ) , used where masonry or rock is not avail able, consists o f a hollow wrought-iron post 3J inches in outer diamter and 4 feet in length. I t is sp lit at the bottom and spread out to a w idth o f 10 inches in order to give a firm bearing on the earth, and is set about 3 feet in the ground. A bronze or aluminum-bronze cap is riveted upon the top of the post. A th ird style of bench mark w ith abbreviated lettering (B and D, PI. I ) , is used fo r unimportant points. This consists of a special copper nail 1 | inches in length driven through a copper washer £ inch in diameter. The tablets as well as the caps on the iron posts are appropriately lettered, and cooperation by States is indicated by the addition of the State name (G, PI. I ) . Another form used in 1896 and 1897 was a copper rod.

(11) IN T K O D T J C T IO N .. 7. 4 inches long and 1 inch in diameter fastened into masonry or solid rock by d riv in g it on a brass wedge placed in the bottom of a ver tical hole, so that the top o f the bolt was horizontal and thus formed the bench mark. The numbers stamped on the bench marks described in the fo l lowing pages represent the elevations to the nearest foot as deter mined by the levelman. These numbers are stamped w ith A -inch steel dies on the tablets of post caps, to the le ft o f the word “ Feet.” The office adjustment o f the notes and the reduction to mean sea level datum may so change some o f the figures that the original markings are 1 or 2 feet in error. I t is assumed that engineers and others who have occasion to use the bench-mark elevations w ill apply to the Director o f the United States Geological Survey, at Wash ington, D. C., fo r the adjusted values, and w ill use the markings as identification numbers only. Datum.—A ll elevations determined by the United States Geolog ical Survey and the United States Coast and Geodetic Survey are re ferred to mean sea level, which is the level that the sea would assume i f the influence of winds and tides were eliminated. This level is not the elevation determined from the mean o f the highest and the lowest tides, nor is it the h a lf sum o f the mean of all the high tides and the mean o f all the low tides, which is called the half-tide level. Mean sea level is the average height of the water, all stages of the tide being considered. I t is determined from hourly observations made by means of tid a l gages placed at stations where local condi tions, such as long, narrow bays, rivers, and like features, w ill not affect the height of the water. To obtain even approximately correct results these observations must extend over at least one lunar month, and i f accuracy is desired they must extend over several years. A t ocean stations the half-tide level and the mean sea level usually differ but little . I t is assumed that there is no difference between the mean sea levels as determined from observations in the A tla n tic Ocean, the G ulf of Mexico, and the Pacific Ocean. The connection w ith tid a l stations fo r bench marks in certain areas that lie at some distance from the seacoast is s till uncertain, and this fact is indicated by the addition o f a letter or word to the rig h t o f the word “ D a tu m ” on tablets or posts. For such areas corrections fo r published results w ill be made from time to time as the precise-level lines of the United States Geological Survey, the United States Coast and Geodetic Survey, or other Government or ganizations are extended. T opographic maps.—Maps of the follow ing quadrangles, w holly or p a rtly in New Y ork, have been published by the United States Geo logical Survey up to March 1, 1918. They may be obtained, unless.
