It was passing off as drainage for some time after May Ist. - 
was a dry month, and the He rainfall scarcely exceeds the drai 
age, as shown by lysimeter No.1. But No. 2, being deeper, 
more conservative than No. lin this month. This one gay : 
very little drainage, most of which was during the last night 
the month, and shows a larger amount of moisture held or ev

An element which adds to the above difference is the inel 
of considerable drainage which really belongs to the June re: 
A heavy rainfall after 6 p. m, May 31st, amounted to 2. 
inches. At 7 a. M. before the drainage was turned off an 
measured, several litres of drainage water had passed off fro 
each lysimeter. This rapid spans was so unexpected that :
