MANURES AND HUMUS IN. SOIL. 1€@1 
beans are drilled in drills about 24 inches apart and 
cultivated carefully till they cover the land, when 
their shade suppresses weeds. 
To get a money crop out of soy beans and yet 
have a hot of humus-making material is easy. One 
does it with hogs, turning them in after the bean 
crop is mature and letting them harvest the beans. 
Afterward the stems remaining with many leaves 
will be plowed down. 
Soy beans respond well to fertilization with phos- 
phatic fertilizers. The larger grows the soil-build- 
ing crop, whether of soy beans, cowpeas, crimson 
clover or anything else, the larger the alfalfa will 
grow after it. Therefore fertilizer applied to the 
cover crop is all to the good. 
Crimson Clover (Trifolium incarnatum).—One of 
the most charmingly beautiful clovers is crimson 
clover, the trifolium of the English farmer. It is 
an annual clover. Sown in summer it makes a fall 
and winter growth (if there is any open weather) 
blooms in May, ripens its seed and dies. It is of 
no use sown in the spring. It is much used in Eng- 
land, France and the Middle Atlantic States of 
America. It is a good forerunner of alfalfa. This 
plant is remarkably cold-resistant and in suitable 
soils grows during every warm spell of winter. It 
enriches soils admirably if it has itself the right 
bacteria at work on its roots. On some soils where 
it is new it needs inoculation. Crimson clover is 
sown in late summer or early fall, usually as a 
eatch crop after corn or garden truck. It makes
