Trials of Artificial Manures. 
but still, thanks to the rooks and heavy rolling, plenty of plant 
was left. The wheat, until it came into ear, notwithstanding the 
drought, which in this part of the country was uninterrupted, 
looked admirably. When however it had attained that condition 
it fell away, and apparently withered from sheer lack of moisture ; 
nor did I conceive that it would average above 18 bushels per 
acre. It was cut with scythes on the 10th of August, and was 
housed on the 20lh — for the results I must refer to the subjoined 
table, in which, in addition, I have given the cost of manures, the 
proceeds derived from each of the crops, and the gross and net 
amount, after deducting the cost of manure, derived to me from 
the experiment. The rent paid for the land, tithe free, is 50s. 
per acre. 
The effect of these diflferent manures upon the growth of tur- 
nips, taking the greatest and smallest produce, and comparing 
them, is this : — 
No. Tons. Cwt. No. 
5 produced . . .7 10 more than ... 1 
3 ,, ... 5 12 
2 ,, ... 4 10 
4 ... 2 16 
6 ... 2 4 
The relative efficiency of the manures, however, undergoes a 
most extraordinary change as far as the growth of wheat is con- 
cerned ; for adding the head and tail corn together produced on 
each acre, and testing their relative produce as we did the last, 
we find the following to be the result : — 
No. Bush. Pecks. No. 
2 produced ... 7 2 more than ... 3 
1 ,, ... 6 2 ... 3 
5 ... 3 2 ,, ... 3 
4 ... 1 0 ... 3 
6 ... 0 3 ... 3 
Now, after guano, which upon the two crops gives the greatest 
profit to the farmer, it will be observed that the mixture of dung 
and Daniel's manure stands second. I had never given this com- 
post previously a fair trial, but had in various ways, and with 
different quantities, unsuccessfully applied Daniel's manure by 
itself. 
The result, however, of this experiment, conducted for two 
years, leads me to infer that this manure, when properly mixed 
with farm-yard dung, will be most advantageous, saving much 
expense in leading, and giving at any rate an equal profit — in this 
case a considerably larger one than would be derived to the 
farmer by the application of double the quantity of dung un- 
mixed ; and indeed in this view I am corroborated by a commu-
