ROOT CROPS FOR FARM STOCK. l8l 



varieties,) and the "Yellow Ovoid" and "New Kinver 

 Globe," both yellow kinds. The average weight of the 

 crop of an acre of Mangels is forty tons; though in some 

 soils they have yielded double that weight. Of course, 

 their cash value, as compared with hay, (rating hay at 

 $15 per ton,) will vary largely under different circum- 

 stances, but Mr. William Crozier considers the average 

 value of Mangels, for stock-feeding purposes, to be $4 

 per ton, or $160 per acre. While hay would be, under 

 the same condition, (estimating two tons per acre,) only 

 worth $30 per acre, the expense of seed, manure, and 

 cultivation of the Mangels, at the utmost, need not exceed 

 $80 per acre; so it is clearly seen that the crop for feed- 

 ing purposes is a profitable one. 



TURNIP CULTURE. 



What has been said on the modes of culture for Man- 

 gels may be applied to Turnip culture, except as to the 

 time of sowing. The Swedish or Ruta Baga varieties of 

 Turnip should be sown, in this latitude, from May 25th 

 to June 25th, and the Yellow Aberdeen, or strap-leaved 

 kinds, from July ist to the middle of August. When 

 sown at these dates, the distance apart may be the same 

 as for Mangels, but both of the classes may be sown a 

 month later; that is, the Ruta Bagas may be sown from 

 June 25th to July 25th, and the strap-leaved kinds from 

 the middle of August to the middle of September; but 

 when sown thus late they should be, both between rows 

 and between plants, one-third closer. The varieties that 

 I find best are, "American Ruta Baga" and " Purple-top 

 Ruta Baga;" of the strap-leaved kinds, "Red-top Strap- 

 leaved " and " Yellow Aberdeen." Mr. Crozier's estimate 

 of the value of Ruta Bagas, as compared with hay, (at
