the hay used — the altercrop, similar to that rolerred to in a 
previous experiment, containing 2'*d per cent, of nitrogen, sup- 
plied in all 519 lbs. of nitrogen, to which that in the straw — 
estimated at 0*5 per cent. — added 31 lbs. more, or 550 lbs. in 
all, instead of the 642 lbs. of nitrogen contained in the dung. 
The inequality was not as great as in the preceding experiment. 
The result was that —

Plot No. 5, dressed with dung, produced 18 74 
„ No. 6, manured with chopped straw and hay, produced 18 58 
or very nearly an equal bulk.

"This was a subject of special interest to the farm at Vaujours, 
besides having been much debated elsewhere. The advocates of 
liquid manure, on the one hand, had maintained that the action 
of manure is quadrupled by dilution ; its opponents put into the 
mouth of an eminent agriculturist a statement (which he did not 
confirm) that the faeces of 48 cows, distributed over 25 acres in 
a liquid form, were of little use, except for dissolving the guano 
which he also applied." To test these contending assertions, two 
plots, 7 and 8, adjoining the previous six, were manured at the 
rate of 24 tons per acre. To No. 8 the manure was applied in 
the usual manner ; with No. 7 this course was adopted : — The 
manure was mixed with 3J- times its weight of water 36 hours 
before use ; it was then well stirred and macerated over-night. 
The solid matter (remains of straw and hay) was then strained 
off, and one-half of the liquid applied to the land and hoed 
in at once, at the same time that No. 8 was manured, the other 
half being kept in reserve. 
Both plots were sown with Indian corn, broadcast, on the 18tb 
of May ; and on the 9th of June, after a showery interval, the 
other half of the liquid manure was applied to No. 7, the Indian 
corn being then well up and strong. To the end of June — the 
weather being then damp — no difference was perceptible between 
the plots ; after that, in the hot months of July and August, 
No. 7 showed a decided advantage. On the 7th of September the 
crops on each piece were cut with the sickle and set into stooks, 
where they remained till October 17th, when both were weighed. 
The climate of Vaujours being unsuited for the ripening of 
this grain, account could only be taken of the gross weight, which 
was —
