 observer in Marrh, 1894. Latitude, 44 deg. 35 min. north; longitude, 73 deg. IS min. west; 

 elevation, 304 feet. 



The meteorological station is located at the summit of a slope 

 on the north side of the Grasse river, which is about 300 feet dis- 

 tant. Although within the limits of the village, the station has a 

 very open exposure. 



The thermometers are secured to the northern wall of a frame 

 building, at a distance of 3 feet from the northwest corner. A 

 screen toward the west cuts off all direct ravs of the sun; but to 

 prevent direct radiation to the thermometers from the ground in 

 the afternoon, a shelter having louvred sides and front, with a solid

 are now placed about 5^ feet above the ground. 



The rain-gauge is located about 30 feet from the house, and is 

 also about the same distance from the barn. The height of por-
