A barometer located in a room on the first floor of the house 

 was found to be out of adjustment and was returned to the central 

 oflSce for correction. 



The rain-gauge is fastened at the back of the shelter, its top 

 being well above the roof and 7 feet from the ground. 



ST. LAWRENCE VALLEY — ST. LAWRENCE COUNTY. 

 Station, North Hammond — Mr. C. A. Wooster, Observer. 



Established (by the National Service with a standard thermometer) in November, 1888; 

 and completely equipped by the State Service in December, 1889; latitude, 44 deg. 30 min. 

 north; longitude, 75 deg. 40 min. west; elevation, about 340 feet. 



The station is situated in the open country 6 miles north of the 

 Hammond depot of the Rome, Watertown amd Ogdensburg rail- 

 road, and about 1 mile from the St. Lawrence river. Northwest- 

 ward from the station the surface of the country is nearly flat, with 

 a gradual slope toward the river; whilst toward the east, and 

 300 feet from the station, the general surface rises some 30 or 40 

 feet. There are no high hills in the vicinity of the station. 



The dry, wet and maximum and minimum thermometers are ex- 

 posed on the northwestern side of a wing of the observer's house, 

 and under the roof of a piazza 5 feet wide. The instruments are 

 secured to the wood work of the wing 6 feet above the floor and 9 

 feet above t'he ground. The room witbin is heated throughout 

 the year; but as a check, a standard thermometer located in a 

 shaded position away from the veranda is read at each observation 

 and thus far the results have agreed very closely. The sun's heat 

 is excluded from the piazza until late in the afternoon, when the 

 floor and the walls are liable to radiate their heat to the instru- 

 ments. Efforts have been made to remedy this defect. 



The rain-gauge is located about 20 feet west of the wing of the 

 house (1^ stories in height), and a distance from a low outbuilding 

 equal to the height of the latter. The top of the gauge is about 5 

 feet above the ground.
