of from 27°03 tons of canes per acre to 29'06 or 2°03 tons 
per acre per annum. Manures on land not limed gave an 
average yield of 28°8 tons, whilst on limed land the result 
was 30'1 tons, an increase of 1°3 tons per acre per annum 
due to lime, But an examination of the detailed tables 
shows that in some instances the average results over 
the five crops on the limed land were less than those of 
the not limed land, and as this was probably due either to 
soil or climatic conditions or to irregularities in the 
springing of the canes, I consider that if these were 
eliminated, the effe€ts due to lime would be more accu- 
rately shown. Eliminating these results, there appears 
to be an average annual increase of 3’9 tons per acre on 
the unmanured land and one of 2'9 on the manured land. 
Mr. SCARD’S results show strikingly how the effeéts 
of lime are modified by soil and climatic conditions, as 
the following were the average gains or losses apparently 
due to lime on each of the estates on which the experi- 
ments were continued during the five crops :—

At the Botanic Gardens our experience has been in ac-

Vreed-en-Hoop. On the plots without manure we obtained:
