The cowpeas turned under in the two year rotation gave greater numbers of bacteria than the ordinary two year rotation at the first three samplings, but at the last date a slightly smaller number was observed, due in part probably to a somewhat lower moisture content. The numbers found were in every case lower than those obtained under the three year rotation. The rye as a green manure in every case gave smaller numbers of bacteria than the ordinary two-year rotation, the differences in moisture content being insufficient in most cases to account for the smaller numbers. The continuous cropping to clover in every case reduced the number of organisms, this reduction appearing very prominently even when no differences in moisture content were recorded. The four-year rotation of corn, corn, oats, and clover, in only one case showed a gain over the twoyear rotation, but the results obtained here were probably due to the difference in the crops grown during the season of the experiment. The difference in cultivation and consequent aeration and moisture would probably account in part for the lower numbers. THE EFFECT OF DROUGHT. Comparing the results at the different samplings in most cases they were rather uniform; with some exceptions the same differences appeared in each case, being more prominent at those dates when the moisture content of the soils was the greatest. There were fewer numbers recorded at the second than at the first date in practically every case, and this corresponded to lower moisture content in the soils. Between the second and third sampling the weather was very dry and probably the bacterial content of the soils went very low. The numbers...
