THE TURNIP. 191 



good crop covering the entire surface, and exhibiting 

 the appearance seen in figure e (p. 187). 



The product of the turnip crop, though always 

 valuable, varies much according to the soil, manure, 

 and culture. The average in this country may be 

 stated at about six hundred bushels per acre, though 

 crops of one thousand bushels are so common as to 

 excite little surprise or remark. The Swedish tur- 

 nip is more solid and heavy than the common turnip, 

 and its nutritive properties are in about thg same 

 proportion. Dickson, in his survey of Lancashire, 

 states " that, on weighing a Winchester bushel of 

 good roots of the ruta-baga and the common turnip, 

 the first weighed 88 lbs. and the latter only 60, a 

 statement which has been confirmed in many in- 

 stances by other experiments." Davy states the nu- 

 tritive matter in the common turnip at 40 parts in 

 1000, and that of the ruia-baga at 64 in 1000 ; and 

 the rate at which they are eaten by animals shows 

 tlidt the chymist was not far from being correct in 

 his estimation of their respective products. In the 

 Northumberland Agricultural Report it is stated that, 

 " on the 16th of March, four tups of the New Lei- 

 cester breed were put up in one pen, and eight 

 draught ewes in another, to be fed on common Nor- 

 folk globe turnips, freed from their tops and fibrous 

 roots. In eight days the four tups ate 1003 lbs., or, 

 on an average, 31 1-2 lbs. per day. In eight days 

 the eight ewes ate 895 lbs., or, an average, 15 1-2 lbs. 

 per day." 



The' whole were then put on Swedish turnips, 

 sliced, weighed, and given regularly three times a 

 day ; of which, in eight days, the four tups ate 553 

 lbs., averaging 17 1-2 lbs. per day. The eiglit ewes, 

 in the same time, ate 544 lbs., averaging 8 1-2 lbs. 

 per day. 



It maybe remarked, however, that an experiment 

 in November might not show so great a diiference as 

 the above, as the common white turnips grow light
