There are numerous varieties of carrots, but the best known early 

 varieties are Early Short Scarlet and Early Scarlet Horn; for medium 

 early, Model, Danvers Half Long Orange and Danvers Half Long Scarlet, 

 Oxheart and Rubicon are popular. Long Orange is the leading late long- 

 rooted variety. 



For the early crop, seed should be sown as early in the spring as the 

 ground can be prepared. It is customary to allow about a foot of space 

 between rows for the early varieties and fifteen inches for the late. The 

 early kinds may be thinned to stand two or three inches apart in the row ?

 cellars, where the roots should be covered with moist sand or soil.

 and second, for the heads to "bolt" or "button" instead of forming hard,
