as a Manure for Ttirm'ps.

The first and final effects of both sorts may be seen by comparing the 
results of the applications Nos. 1, 6, 9, and 14. Thus — 
No. 1. — 16 bush, bones give . . 10 tons 3 cwt. 4 st. 81b. per acre. 
6. — 8 „ dissolved give 16 tons 1 cwt. 3st. 61b. „ 
9. — 4 „ dissolved give 12 tons 11 cwt. 6 St. 41b. ,, 
16. — -4 ,, dissolved give 14 tons 11 cwt. 7 St. „ 
Nos. 6, 9, and 14, too, it will be observed, also took the lead from the 
commencement. 
6. That the peculiar effects arising from the application of dis- 
solved bones are not merely an augmented crop at a decreased cost 
in manure, but a crop showing an abundant, healthy, and extra- 
ordinarily quick-growing young plant, a decided tendency to form 
bulbs at a much earlier period than common, and less liability to 
damage from the enemies which usually attack the turnip in the 
early period of its growth. 
It will be observed that there was a gain in the growth of the dis- 
solved plots of ten days in the first month. It may be added, that there 
was a gain of a month at the end — the dissolved portions being ready for 
use several weeks before any other. 
7. That all sorts of bones are well adapted for use in this man- 
ner ; but that it is a bad economy to burn or boil the bones in 
order to prepare them, as we waste a valuable manure in the or- 
ganic matter, and the total effect arising from such will not be the 
same that it would had they not been subject to a process which 
materially reduces the weight of manure applied. If, however, 
bones are to be bought for this purpose, the same rule will hold 
that we have laid down before, as regards bones in their ordinary 
state. Thus, if we buy by measure, it will be advisable to have 
the animal matter in the bone, as it does not materially augment 
the bulk of the bone ; but if we buy bi/ iceiyht, we cannot have over 
little of the animal part, as the earthy is comparatively the more 
valuable : and when we pay by weight, we cannot have too great a 
proportion of the best material. 
All the sorts of bone are augmented iu their action by being dissolved 
( Vide Nos. 6, 7, and 8). The animal part in No. 6, it will be seen, has 
some effect, and therefore it should never be toasted, as the action of the 
acid removes the influence which it possesses in ordinary cases over the 
action of the earthy part. In No. 6 it will be seen that there is lOst. 81bs. 
more matter of the bone applied than in No. 8 ; this 10 st. 8 lbs. being 
the amount of the animal substance in the 24 st. of bones applied. If now 
No. 8, instead of ISsi. 6 lbs., had had 24 5^. of the earthy part of bone 
(i.e. 10 St. 8 lbs. extra), it would, no doubt, have equalled and perhaps 
surpassed in results No. 6, which had 13 st. 6 lbs. of the earthy and 
10 St. 8 lbs. of the animal part of bones applied; as, under present cir- 
cumstances, there is not a great difference in the weight of the crop pro- 
duced. If, therefore, we can buy by weiglit the dry earthy parts of 
bone for this purpose, we had better have it than the same price for the
