Production of small fruits is increasing. Strawberries are the most 
important small-fruit crop, with raspberries and Logan blackberries 
gaining in importance upon soils which do not dry out too early in 
the season. (See fig. 4.) Logan blackberries seem to be particu- 
larly adapted to the climatic conditions of western Oregon and Wash- 
ington, and, as yet, have not been grown with success in other sec- 
tions of the country. The future commercial importance of this crop 
may have some bearing on the development of the lo^ged-off lands 
in western Washington and Oregon, to which the crop is Dest adapted. 
Blackberries require a moist soil and therefore are not extensively 
grown on the uplands. Currants and gooseberries do well on the drier 
soils, but as yet have not been generally grown for commercial pur- 
poses. 
The yields as given in Table 6 are the averages for the farms 
included in the investigation of the amount of fruit harvested on bear- 
ing acreage. No account was taken of the loss caused by waste and 
spoilage in the field. The yields, especially of blackberries and rasp- 
berries, are considerably less than in lower and more favorable areas. 
The "other crops" consist of orchard fruits and vegetables for live- 
stock (kale, mangels, and carrots) which have little commercial sig- 
nificance.

TENURE. 
The facts that most of the farms are small and many of the farms 
are looked upon primarily as homes, tend to discourage the growth 
of tenancy in this area. More small-fruit farms are rented than farms 
of the other types. A few of these farms are rented to Japanese farm- 
ers, who generally devote the entire cleared area to strawberry grow- 
ing. In practically all cases rent is paid in cash. 
On account of the small number of tenant farms in this area, all 
of the farms are analyzed only on the farm basis. 
RECEIPTS FROM FARMS OF THE DIFFERENT TYPES.
