Varieties of Roots.

yellow, white and purple are met with. From one-half to two-thirds of 

 the root may be below ground; thus in a root 20 inches long, 10 to 13 

 inches will be below ground. This is important as it limits the successful 

 growth of such varieties to deep friable soils which can be fitted to a 

 good depth. 



The half-long tapers from the shoulders to the tap root, and is like 

 the long in appearance but the length is less than three times the greatest 

 width. 



The ovoid is frequently about two or three times as long as it is 

 broad, and tapers to the crown and the tip of the root. The skin is of 

 various colors, red, yellow and orange being most common. About one- 

 half the root may be below 

 ground, hence, owing to their 

 short length, they are better 

 fitted for shallow soils than 

 the long forms. 



The tankard is about two 

 to three times as long as broad 

 and differs from the half-long 

 in that its width is almost uni- 

 form throughout its entire 

 length. The Golden Tankard 

 is one of the most common, 

 although the Crimson Tank- 

 ard, which has a crimson or 

 rose-colored skin, with crim- 

 son rings in the flesh, is also 

 well known. Four inches in 

 diameter and 10 to 11 inches 

 in length is a common propor- 

 tion. Generally rather more 

 than half of the root is above 

 ground, and in roots above 

 average size, for this district, 

 but five inches will be below 

 the surface. 



The globe form is spher- 

 ical or nearly so. A common 

 size in this locality is from 

 four to seven inches in diameter 



Fig. 42. — A typical half-sugar mangel. A 

 good type to grow. It does not vary in yield 

 so widely as do regular mangels, and it 

 yields well in dry matter. Background

The Yellow Globe is the most com- 

 mon, although red and orange varieties are frequently met. Frequently 

 two-thirds to four-fifths of the root is above ground, hence this form is 

 particularly adapted to shallow soils. It is readily pulled.
