Prof. Way has made a series of elaborate examinations 
on drain-waters furnished by Mr. Paine, of Farnham, 
Surrey. The waters were collected from the pipes (4-5 
ft. deep) of thorough-drained fields in December, 1855, 
and in most cases were the first flow of the ditches after 
the autumn rains. The soils, with exception of 7 and 8, 
were but a few years before in an impoverished condition, 
but had been brought up to a high state of fertility by ma- 
nuring and deep tillage. (Jour. Roy. Ag. Soc., XVII, 133.)
