Saint Helens. Cascades spring from every 

 crevice; the river foams over boulders and thru 

 broadens into a placid stream. At Castle Rock 

 in Morrow County there is another beautiful 

 gorge, and above this point the river channel 

 becomes narrow and tortuous.

In the eastern section, cut off from sea winds 

 by the Cascades, extremes of temperature oc- 

 cur in winter and summer, and there is also a 

 great daily range, due to the high elevation, 

 have been known to occur every month 

 during the year. This section of the state is 

 dry, the annual rainfall being only from 

 eight to twenty-two inches. In the Cascades 

 the amount of rainfall is greater, but is only 

 one-third of that on the. slopes of the Coast 

 Range, where, it ranges from 75 to 138 inches

Colorado in weird beauty. Crater Lake, Na- 

 tional Park, is .-mother of the beauty spots of 

 the state. The lake, which is in the sunken 

 volcanic crater of Mount Mazama, is of won- 

 derful clearness and great depth. It lies 6,239 

 feet above the sea and is surrounded by dense 

 forests and mountain walls of rock. The Kla- 

 math Lakes are also noted for their scenery. 



Climate. There are two distinctly different 

 climates in Oregon, belonging to the contrasting 

 sections of the state. West of the Cascade 

 Mountains the climate is mild, moist and 

 equable, much like that of the British Isles. 

 The winters are mild and humid, and the sum- 

 mers, because of the trade winds, are cool and 

 cloudless.

Agriculture. The improved land in farms 

 is over 4,300,000 acres, or about one-fifteenth of 

 the total land area. The greatest proportion of 

 land used for agriculture is in the northern 

 third of the state and in the counties of the 

 western section. East of the Cascades irriga- 

 tion is generally necessary. In some districts 

 there are late frosts; other sections contain 

 alkali deserts wholly without vegetation, and 

 still others are suitable only for grazing. The 

 most valuable farm land is in the Willamette 

 Valley, where every crop of the temperate zone 

 can be raised. This fertile valley and those of 

 the Rogue and Hood rivers are famous for the
