EASTERN PLATEAU — TIOGA COUNTY. 

 Station, Waverly — Mr. T. P. Yates, Observer. 



Established by Signal Service In August, 1SS7; latitude, 42 deg. 01 min. north; longitude, 

 76deg. 34 min. west; elevation, 824 feet. 



This station is near the northeastern limits of the village of 

 Waverlj, and its surroundings are more like an open country than 

 might be expected from its proximity to the village. The station 

 is about two-thirds of the distance between the gradual slope from 

 the Susquehanna river and the hills a mile away, which form the 

 northern boundary of the valley. The elevation of the hills in 

 this vicinity, on either the north or south side of the valley, prob- 

 ably does not exceed 300 to 500 feet. 



The dry and wet bulb and the maximum and minimum ther- 

 mometers are exposed in a shelter 40 feet east of Mr. Yates' house. 

 The shelter consists of a double unpainted box open at the bottom 

 having an air space 1 inch in width between the sides, and with 

 slat work at the top opening to the ventilators in the ridged roof. 

 Some additional ventilation is also obtained through a few spaces 

 from one-eighth to one-fourth of an inch in width between the 

 boards at the sides of the shelter. The dimensions of the shelter 

 (outside) are 2 by 3 feet at the base and 2^ feet in height, exclusive 

 of the roof. The thermometer supports are secured to a board 

 near the back or south side of the inner box, and the door of the 

 shelter opens toward the north. The height of the thermometers 

 above the sod is 4^ feet.
