DEPARTMENT OF ( fig. 3), is faced with galvanized iron so shaped as to form two par- allel lubes running the entire length of the board. At the top end the tubes are funnel shaped. At the bottom end they empty into a kind of hopper. To this hopper a spring and a lever are attached, by means of which the mouth of the hopper can be opened or closed as desired. At the top of the back of the baseboard a handle is at- tached. At the bottom there is a flange by which the depth of plant- ing can be regulated. One man can operate the planter very easily. Rapid progress can be made if the seeds to be planted are carried in a pouch attached to each hip, cotton seed in one and beans or peas in the other. One kind of seed can be dropped into one of the tubes and the other kind into the other tube. Then, by thrust- ing the nose of the planter into the ground at a marked point and giv- ing the planter a forward lifting movement, the seeds may be depos- ited at a uniform depth in the moist soil. The spring on the hopper closes the latter automatically as the planter is lifted again. As the op- erator steps forward to plant the next hill he can step lightty on the hill just planted, thus compacting the soil about the seeds, meanwhile dropping more seeds into the tubes, to make ready for further planting. Fig. 3.—Hand corn planter, designed by the Office of Corn Investigations, suc- cessfully used at San Antonio in 1917 in planting delintcd cotton alone and in combination with peas and beans. The use of a planter of this type ap- pears to have a number of advan- tages over the usual method of hand-dropping progeny rows. (Pho- tographed July 2, 1917.) METHOD OF PLANTING DRILLS. IN Nurse planting in drills is prac- ticable only with delinted cotton seeds, for reasons already given. With these it becomes a simple operation, since the ordinary corn planter can be used. Mixture
