117. Lime reqnh'ement of soils. — A test of soil with litmus paper to 

 determine whether lime is probably needed. This is to be followed by 

 a trial of lime on a small plot. The proper kind of litmus paper and 

 directions for the trial will be furnished. 



118. Spraying for wild mustard. — Mustard can be easily killed by 

 proper spraying with copper sulphate or iron sulphate. 



119. Cost and profit or loss in the production of any crop. — Dupli- 

 cate blanks for keeping account with the corn, oat, or wheat or other 

 crop will be supplied. One copy to be returned to the college. 



120. Reduction of labor by use of more horses per man. — Under 

 some conditions a saving can be made by having each man drive more 

 horses. This is a matter that cannot readily be arranged as an experi- 

 ment, but correspondence is desired with those who feel that their con- 

 ditions warrant a trial of this subject and reports of the success or failure 

 of such efiforts are desired. 



121. Potato cultural test. — The college has obtained good results in 

 growing potatoes by what has come to be known as the Cornell method. 

 Many farmers have likewise increased their yield by this method. It 

 gives best results on gravelly or sandy soils. 



122. Buckivheat: Cultural test. — Plow one plot early and harrow 

 frequently until seeding time. Till other plat in the customary way. 



123. Crop rotation. — A comparison of the present system with one

 order to secure results. 



II. PLANT SELECTION AND BREEDING. 



J. W. GiLMORE. 



124. Potatoes. — An experiment in selection by hills for the purpose

125. Corn. — An experiment in selection and breeding with a view to 

 developing an improved strain, (i) For silage or (2), for grain. 



126. Oats. — An experiment in selection by individual plants for the
