acre. This dressing, it must be allowed, is a considerable one, 
and, though here justified, it can well be understood. that the 
cost of it might make the ordinary farmer hesitate. It was 
therefore thought desirable, in extending the liming experiment, 
to endeavour to ascertain whether smaller applications of lime 
might not be efficacious : accordingly, the new scheme was 
made to include applications of 5 cwt. (plot 2aa), 10 cwt. 
(plots 8aa and 8bb), and 1 ton (plot 5b) per acre, as well 
as a repetition of the 2 tons per acre on plot 2bb. The lime 
used contained 79*34 per cent., of lime (CaO). It was bought 
ground, then slaked with water under cover, left for a few 
days to crumble down, then carted out and spread on the land 
and harrowed over. These various dressings were given on 
January 19, 1905. It was not expected that any result would 
be noticed in the crop of 1905, as the lime would necessarily 
take some time to work. Farmyard manure, made as usual 
in the feeding boxes by bullocks, was spread on plot lib 
on February 18, and rape dust on plot 10b on February 20. 
Cold weather followed upon this and made the crop appear 
very limp. 
The nitrogenous top-dressings were applied, the first halves 
of the heavier dressings on April 17, and the second halves and 
single dressings on May 15. The different plots came on very 
fairly except 2a (ammonia salts only), which was almost bare, 
and presented quite a contrast to 2b which had had the same 
treatment with lime in addition. Heavy rains fell early in 
June and the wheats were all in bloom by June 24, after 
which, under the influence of dry weather, they ripened fast 
towards the end of July. On August 14, they were cut, and 
were carted on August 24, being finally threshed and weighed 
on November 3, after which the corn was valued by an expert. 
The general yield was an average one and much in excess 
of that of 1904. The unmanured produce was 14J bushels per 
acre (plot 7, this being the more reliable owing to the influence 
of surrounding trees on plot 1) as against 7*4 bushels in 1904. 
The highest yield was from plot lib (farmyard manure), 32*45 
bushels, the biggest crop with artificial manures being 26*57 
bushels (plot 9a). Ammonia salts alone (plot 2a) gave no crop 
worth reaping, but with the lime (2 tons applied once, Decem- 
ber, 1897) yielded just over 10 bushels, which was as much as 
nitrate of soda alone gave. The gradual diminution of crop 
with nitrate of soda is noticeable and points to still further 
interesting results being forthcoming in the future. Used 
with mineral manures, ammonia salts (plot 5) gave a higher 
yield than did nitrate of soda (plot 6). When, however, heavier 
dressings of the salts were used (plots 8a and 9a) the ammonia 
salts showed the same signs of failure as they did on plot 2a,
