The following are some of the many other experiments you might 

 undertake:

INSTRUCTIONS. 



1. Get advice from your elders as lo hest time and manner of do-

'>. Under the proper date and number, note when and how each 

 plat is prepared and planted.

7. Observe when the seeds in each plat "come up," the per cent, of
