tells us that Silver Lake, which now covers an area 

 of approximately 70 square miles, was dried up during 

 the years of 1898 and 1399 and crops of oats 7 feet 

 high, were raised on land now inundated by from 3 to 

 10 feet of water. Precipitation records show also 

 that there were very few dry years. In the early fif- 

 ties, immigrants made a well-defined trail which is 

 yet visible in places across a point in Goose Lake 

 now covered with 10 feet of water. For a Short period 

 in 1869 the lake overflowed into Pitt River. The solu- 

 tion of these two facts is that the lake level fluctu- 

 ated 25 feet in about I;? years. The level of the lake 

 at the present time is about 13 feet below the Pitt 

 River outlet. V/eather records taken at Silver Lake and 

 Lakeview have no particular value except for comparison. 

 Observation of the amount of snowfall at various ele- 

 vations and different localities show tint the data 

 from the two stations, both of which are over 8 miles 

 from the natural forest and 100 miles apart, cannot be 

 used even to give a general idea of the country and 

 much less for the determination of the habitat of any 

 particular area, except where the readings have been 

 made. These figures show, however, that occasional 

 soil tests and pscyhometer readings have no particular 

 value and that small areas must be determined se-
