crops grew on the ends of the check plats, it would seem 

 that the phenomenftijmight possibly be due to the influence 

 of the crop. But plats 5 and 9 show the same differences, 

 and the ends of these plats produced practically the same 

 crop as their middles . 



The moisture content November 21st. (Table "C",III) 

 was contrary to appearances higher than on November 20th. 

 (Table "B", III). No precipitation or freeze occurred 

 between the taking of the samples. On November 20th. the 

 surface was sticky. The soil cylinders were sunk one 

 fourth to one half inch beneach the surface, tljus eliminat- 

 ing this portion, but the soil beneach this was also 

 notably more sticky than the day following, when it worked 

 fairly wejl. It would seem that the freeze localized the 

 moisture, and after the thaw it was redtstributed. There 

 woitld seem to be a correllation between this and the 

 increase in pore space noted above. 



On the whole, the plats which were not cultivated 

 (Plate 2, 3, 5, and 7) show less pore space than the others. 

 Had the samples been taken earlier in the season, perhaps 

 the difference would have been more marked. Plat #2 has 

 a higher per cent pore space than any of the other unculti- 

 vated plats. The mulch had been removed from Plat #3 pre- 

 vious to taking the samples. Further correllations do 



not seem to exist.
