OF AGRICULTURE. 177 



ing. At Aldershot they obtain excellent potato 

 crops ; and at Romford (Breton's Farm) Colonel 

 Hope obtained, in 1871-1872, quite extravagant 

 crops of various roots and potatoes.* 



It can thus be said that while at the present 

 time we give two and three acres for keeping one 

 head of horned cattle, and only in a few places 

 one head of cattle is kept on each acre given to 

 green crops, meadows and pasture, man has 

 already in irrigation (which very soon repays 

 when it is properly made) the possibility of keep- 

 ing twice and even thrice as many head of cattle 

 to the acre over parts of his territory. Moreover, 

 the very heavy crops of roots which are now 

 obtained (seventy-five to 110 tons of beetroot to 

 the acre are not infrequent) give another power- 

 ful means for increasing the number of cattle 

 without taking the land from what is now given 

 to the culture of cereals. 



Another new departure in agriculture, which 

 is full of promises and probably will upset many 

 a current notion, must be mentioned in this 

 place. I mean the almost horticultural treat- 



* Prof. Ronna gives the following figures of crops per acre : 

 Twenty-eight tons of potatoes, sixteen tons of mangolds, 105 

 tons of beet, 110 tons of carrots, nine to twenty tons of various 

 cabbage, and so on. Most remarkable results seem also to have 

 been obtained by M. Goppart, by growing green fodder for 

 ensilage. See his work, Manuel de la Culture des Mais ei autres 

 Fourrages verts, Paris, 1877.
