THE TURNIP CROP. 



The "yellow-top" varieties are rarely met with in cul- 

 tivation to any great extent. Although they are gene- 

 rally quick growers, they are less productive and less 

 hardy than other varieties. 



The yellow globe is one of the best varieties for field 

 culture, with bulbs of a medium size, globular, and grow- 

 ing deep in the soil; leaves small and spreading. 



A Uringham yellow, Jones yellow, yellow Preston, and 

 Chivas' orange jelly, are favourite varieties in different 

 districts. 



The white varieties in cultivation are very numerous. 

 Of these 



The common white globe (fig. 6) is that most generally 

 grown, and is an excellent description of root for early con- 

 sumption. The bulb is globular, skin smooth, and perfectly

fine and small, and tap-root small. 

 The shape varies, with the care be- 

 stowed in selecting the seed-roots, 

 from an almost perfect sphere to a 

 sphere flattened more or less at one 

 or both ends. On rich soils this 

 variety has a tendency to develop 

 itself to a great size, to become 

 woolly in texture, diminished in 

 feeding value, and to exhibit a ten- 

 dency to rot and deteriorate in the 

 field, especially if they be flat at the 

 top, and the weather be wet and 

 changeable. It is, therefore, desirable on such soils, to 

 leave them pretty close together in the drills say 9 or 

 10 inches apart. This gives fully as large a return per 

 acre, by the increased number of smaller roots being more 

 nutritive and less liable to injury than the large ones. 

 They are generally ready for use about the end of Sep-
