THE RUSSIAN FUR-SEAL ISLANDS.

The barometer cistern was 20 feet above sea level. 
The thermometers were hung in a large lattice box on the north side of my house, 
the box covering the window; and the instruments were read through the latter from 
the inside. 
The rain-gauge ^ had to be located very high (9 feet) and in an exposed place to 
keep it from the marauding sledge-dogs. This instrument was not satisfactory in a 
high wind. The wind in blowing across the mouth of the funnel would actually suck 
the air out of the latter, thus preventing the rain or snow from entering. Many a 
time after a considerable rain I have found the rain-gauge dry inside. The actual 
amount of precipitation is therefore greater than shown in the table given below, 
though the tigures in the latter may serve for comparison with those from similar 
localities in the United States, particularly on the Pribylof Islands and in Alaska, 
where the saTiie kind of rain-gauge was in use. 
The following tables I have transcribed directly from the original records. The 
monthly means are those of the means of the three daily observations. The method 
of observing, correcting, and tabulating is that in vogue in the Signal Service, 
and the figures are strictly comparable with those of the other stations of the same 
Service.
