G. 9. — Kale is an important green feed on many poultry farms. One acre of ka

of adding to income is necessary. Increasing the size of the flock is 
perhaps the best means of increasing income if the management of the 
smaller flock has been successful. It is also possible in many cases 
to take on a few acres of bearing small fruit, a unit of up to 1,000 
hens and 2 to 3 acres of small fruit being within the working limits 
for a man and his wife except for the picking season. 
SMALL-FRUIT GROWING. 
Adaptability to soil conditions is becoming an increasingly impor- 
tant factor in successful small-fruit growing in western Washington. 
The best results are obtainable only when each kind is grown on the 
kind of soil on which it has the best chance to succeed. Strawberries 
prefer the well-drained sand and gravelly loams common to this area, 
though they grow on many kinds of soils. (See tig. 10.) In the 
lower and moist areas there is more danger of t lie bloom freezing, 
and the plantsrun Largely to foliage. Raspberries thrive best on the 
sandy and well-drained clay Loams which do not dry out early n\ the 
season. Logan blackberries thrive on land suited for raspberries. 
but do better on clay loams and will stand considerably more soil 
moisture. Evergreen blackberries have a wide adaptability, but 
prefer a rich clay Loam soil which is retentive of moisture. 
Diversification of smallfruitsis often a safeguard to profits on farms 
which depend entirely upon berries for an income. The failure of 
one crop due to disease, weather, and other causes does not then
