Of the three plots printed in italics, F was patchy, owing to 
its having suffered in the drought ; K was defective, owing to 
partial failure of the plot at one end ; while H was quite spoilt 
by its irregularity. 
The table on page 429, obtained by deducting from the 
acreage yield of each plot the yield of the land which received 
no artificials, gives the increase obtained in each case by the use 
of the artificials. The cost of each dressing, at the retail prices 
current at the time, inclusive of carriage, is also given, viz., 
superphosphate 3/. 10s. per ton, Belgian phosphate 3Z. 10s., 
Peruvian guano 10/. 10s., fish guano 71., sulphate of ammonia 
13/. 5s., nitrate of soda 12/., kainit 3/. 5s., and salt 21. per ton. 
It is again to be noticed that the lines printed in italics, viz., 
K, H, F, refer to plots the actual yield of which is no^ to be 
accepted as truly representative of the results due to the manure 
used, owing to the plant having been defective, as previously 
noted. 
It will be seen that the crop produced by dung alone was less 
than 3^ tons per acre. Although about eleven tons of dung per 
acre had been used, it was not dung of by any means high 
quality, and was made chiefly by dairy cows and not kept under 
cover. The following table, showing the yield per acre after 
deducting for the dung which was used throughout, shows that 
artificials gave an increase per acre varying from 1 ton to nearly 
8J tons of cabbages. 
These experiments, made under the conditions obtaining, viz.,
