EXPERIMENT ON THE CULTIVATION QF CABBAGE.

Estimated Value of each Lot. — According to Sinclair's analysis, 

 Drumhead cabbas^es contain 430 trains of nutritive matter and 

 280 grains of fibre per pound, and the average amount of nutri- 

 tive matter in cabbages, as compared with common turnips, is 

 215 of the former to 160 of the latter, and inferior to swedes in 

 the proportion of 215 of the former to 220 of the latter. Taking 

 these as the standard, the following is the amount of nutritive 

 matter per acre of the three lots experimented on, viz. : — 



By this it will be seen that an acre of cabbages is capable of 

 producing a much greater amount of nutritive matter than either 

 turnips or swedes, and this trial must not be taken as the full 

 amount cabbages are able to produce, as they were planted later 

 in the season in order to test them thoroughly against turnips, and 

 to keep up a succession of green food for the cows. I have another 

 two acres in an adjoining field, planted 36 inches between the 

 plants, and 30 inches between the rows, that the reporter is now 

 using, which is proved by weighing to produce at the rate of 37 

 tons 1 cwt. per acre ; this lot was planted on 29th April. The 

 relative value of each lot will be better seen by the following 

 table, where I suppose the " consuming " value of Fostertons to 

 be rather under 10 shillings per ton, or at the rate of £10 per 

 acre, thus : — 



Fostertons, .... 

 Swedes, .... 



Cabbages, .... 



But in order to arrive at the true value we must deduct from 

 each kind any seed or extra labour the one has more than the 

 other, thus : —
