EXPERBIENTS IN POTATO CULTUEE. 113 



sratill, 1 pound 2 ounces; total, 8 pounds 2 ounces. For 

 the seven years, No. 1 produced 2051^ pounds of large and 

 62 pounds of small potatoes. The same number of hills of 

 No. 2, the cut seed, produced in the same time 192| pounds 

 of large and 71| of small potatoes, — the small whole seed 

 producing 13 pounds more of large potatoes and 9| pounds 

 less small ones than No. 2, the seed cut from large potatoes. 



The next experiment is to show the different ends of the 

 potato, No. 3 being the seed end and No. ^4 the stem end. 

 The next view shows the plants as they were June 28 ; the 

 next is a field view taken July 21. These views all show 

 that the seed end produced plants that kept in advance of 

 those that came from the stem end, but for some reason 

 these two hills show more difference than the other eighteen 

 hills in this experiment ; yet ev^ery year during the six years 

 which this experiment has been under trial, the plants from 

 the seed end have started in advance of those that came 

 from the stem end. 



The next view shows the result of this experiment. No. 3, 

 seed end, produced, of large potatoes, 4 pounds 8 ounces, 

 and 1 pound 10 ounces of small; total, 6 pounds 2 ounces. 

 No. 4, stem end, produced, of large potatoes, 4 pounds 4 

 ounces, and of small, 1 pound 2 ounces ; total, 5 pounds 

 6 ounces. For six years the ten hills of each number pro- 

 duced. No. 3, seed cud, 166^ pounds of large potatoes and 

 47^ of small; total, 213| pounds. No. 4, the stem end, 

 produced 141| pounds of large potatoes and 471 of small ; 

 total, 188|^ pounds, — the seed end producing 25 pounds more 

 large potatoes than the stem end, and about the same quan- 

 tity of small potatoes. 



The next experiment is to show the difference between 

 large and small potatoes for seed. The result is not satis- 

 factory, and I cannot help thinking that if the experiment 

 be continued seven years, most of the yearly results will be 

 different ; but I give you the result of this single experi- 

 ment, with the caution not to draw any conclusions to be 

 used, until more trials of the same experiment have been 

 made.
