These several regions have considerable difference in elevation, 

 as exhibited by table No. 1, showing number of stations and 

 approximate elevation above tidewater in 1893 and 1902. In 

 1893 the western plateau comprised fourteen stations, with an 

 approximate elevation above tidewater of 1211 feet, while in 1902 

 the western plateau comprised seventeen stations, with an 

 approximate elevation of 1135 feet. Owing to the fact that the 

 observations are voluntarily made, considerable change in the 

 stations has taken place between 1893 and 1902, many stations 

 at which observations were kept in the former year having been 

 discontinued and new stations at other places substituted. The 

 showing, therefore, of table No. 1 is relative, and merely intended 

 to give a general idea of the approximate elevations of the several 

 divisions. In the case of the northern plateau there are no sta- 

 tions in the higher mountains, and hence that region is inade- 

 quately represented in table No. 1. 



Description of the meteorological tables. Tables Nos. 2 to 8, 

 inclusive, give a meteorological summary at Albany, Buffalo, Erie, 

 Pa., New York city, Northfield, Vt., Oswego and Rochester, for 

 the calendar years 1891-1901, inclusive. Column (11) in these 

 tables gives the maximum precipitation in 24 hours for each year, 

 and column (12) the month in which the maximum precipitation 

 occurred. The utility of these columns in designing sewers and in 

 considering effects of floods is obvious. 



Tables Nos. 9 to 18, inclusive, give the mean temperature of 

 the several climatic areas into which the State has been divided 

 for the water years 1891-1901, inclusive. The mean temperature 

 for the eleven years included in these tables varies from 42.2° per 

 year in the northern plateau to 50.9° for the Atlantic coast region. 



In tables Nos. 19 to 28, inclusive, we have the precipitation 

 of the. several climatic areas of the State for the water years 

 1891-1902, inclusive. The average precipitation varies from a 

 minimum of 34.46 inches in the Central Lakes region to 46.71 

 inches in the Atlantic coast region, or a range of 12.25 inches.
