PRODUCTIONS OF DIFFERENT SECTIONS. 271 



The absence of sufficient rains and dews, however, during the summer 

 jionths at some pointa, renders an occasional resort to irrigation necessary 

 for the productio 1 of corn, potatoes, and articles of a like nature. 



Two crops of some kinds of produce may be raised with success in a 

 single year. 



In tlie vicinity of the Wallamraette, the winters are only a trifle colder. 

 Running water seldom freezes. Snow never falls to exceed the depth 

 of a few inches, and disappears in a very short time succeeding. 



Vegetation in the valleys, and even upon the plains, to some extent, 

 remains green year in and year out. Of course no better climate could 

 be selccteel for stock-raising. 



These remarks may be applied with equal propriety to the other por- 

 tions of the Western Division south of the Columbia and in its immediate 

 vicinity. The country further north, for a considerable distance, posses- 

 ses a climate almost as favorable. The snows of winter, however, are 

 usually more frequent and less transitory in their continuance. 



The cold season is confined almost exclusively to the ti)ree winter months. 

 The heat of summer is moderate and agreeable, generally ranging at 62*' 

 Fahrenheit, above zero, in its mean temperature. 



The wet season of the Western Division usually occurs from October to 

 March of each year, inclusive ; at other times rain seldom falls. During 

 this season it descends in gentle showers, or in the shape of mist, at inter- 

 vals, for about one half of the time. Tiie moisture received into the earth 

 meanwhile, together with the nightly dews and otlier favorable agencies 

 during the summer months, renders the soil adapted to cultivation. 



Back from the valleys and bottoms, the atmosphere is quite wholesome 

 and salubrious. Fevers are seldom known, and pulmonary complaints are 

 equally rare. 



In the vicinity of the Columbia, intermittent fevers are not uncommon, 

 though by no means as bad as in some parts of our frontier States. 



Next in the order before us come the various productions which may 

 be, and are, successfully cultivated in the diflerent sections of this part of 

 our national domain. 



The soil and climate of the Eastern Division have been sufficiently test- 

 ed to know their capacity for producing nearly, if not quite, all the various 

 grains, vegetables, and fruits usually grown in our Nortliern and Middle 

 States. A great variety of wild fruits and vegetables grow spontaneously, 

 in different parts, and in great abundance. 



The soil and climate, as a whole, seem better adapted to the culture of 

 fruits and grains, than vegetables ; and perhaps we might add, for the raia- 

 tug of cattle, horses, and sheep, than agriculture ; though the latter obser- 

 vation is not to be so construed as to allinn that farming may not be suc- 

 cessfully and profitably prosecuted in many parts. 



The Northern Division, or that portion of Oregon lying on the head- 

 waters of the Columbia, in the vicinity and south of Frasier's river, and 

 upon the Chilkeelis, being much colder and more sterile, must necessarilj 

 be regarded in a less favorable light than the country referred to in the 

 preceding paragraph. But, little is known as to its products or the capa* 

 cities o^ ita sou and climate ; yet, it ia said that some particular kind* of
