In commenting- upon tliis table, Mr. Bartholomew says: 
The total weight of straw and grain on the entire tract was 1,528 pounds, the 
62 untreated plats yielding 797 pounds, and the 58 treated ones 731 pounds. The 
average yield per plat for the former Avas 11.72 pounds and for the latter 11.32 
pounds. The total yield of cleaned grain was 258 pounds, being 133 pounds for the 
untreated and 125 pounds for the treated. 
The average yield on both classes was almost exactly the same, viz, 1.95 pounds per 
plat. This shows a difference in favor of the treated plats in the matter of grain 
when we consider that the average product of these plats Avas about one-third of a 
pound less per plat, and that a number of the plats Avere greatly injured by the 
treatment as indicated in the table, showing a marked decrease in the production of 
both grain and straw. Doing away Avitli the passage ways betAveen the plats and 
presuming the rows to be 9 inches apart over the whole tract, this Avould indicate a 
yield of about 17 bushels per acre, which is in marked contrast with the adjoining 
field, where the yield was 30 bushels. Of course in the field the conditions Avere 
quite different. The seed was sown broadcast among cornstalks and thoroughly cul¬ 
tivated in with a fine shovel culthmtor, and stood A r ery thick all over the ground. 
Another rather peculiar thing must be noted regarding conditions. The prepara¬ 
tion of the ground consisted in cultivating and thoroughly harrowing the land, AA 7 hich 
placed it in excellent condition for seeding. A good crop of corn Avas raised on the 
land. This Avas cut and carried off before the cultivating and harrowing. The Avhole 
plat was very smooth, so much more so, in fact, than the adjoining field, that it proved 
an excellent playground for dozens of jack rabbits. Many of the young plants were
