— MOISTURE DETERMINATION — 



All samples for moisture and fertilizer determination 

 were a composite of six borings taken to the depth of 7 in- 

 ches till July 30th. After this date the suiftice two inches 

 was discarded. The soil augur wastiBed in sampling, serving 

 the purpose well except when the soil became extremely dry in 

 the weedy"plats 5 and 9, where it was difficult to get good 

 samples. This difficulty, however, would seem not to affect 

 the value of the results, since if there were any variation 

 from the proper results it would be on the side of conservatism 

 There would be a tendency to secure a higher moiature and per- 

 haps also of nitrogen content on these plats than the actual 

 amount . 



Regularity was observed in the locations at which bor- 

 ings were made , The samples in the corn were taken in the 

 center of the square between the hills in the first^ third, and 

 fifth middles , The first borings were made in the second cross 

 middle from each end, the second from the third, etc. At the 

 ends the first blbring was made three feet from the corn, the 

 second four feet, etc. Care was taken not to walk on the part, 

 where the future borings were to be made. Where slight ridges 

 occurred the boring was made between the furrow and ridge. 



The samples were taken to the laboratory where the 

 moisture was determined and estimated on the basis of dry soil.
