carrot. The long white carrot is of delicate flavour, but does 

 not keep well. Carrot-seeds do not retain their vegetative 

 power more than a year. The carrot is an aliment of the 

 greatest value in the feeding of horses, oxen, sheep, swine, and 

 deer. One of the difficulties in raising a field-crop of carrots 

 is to fence the land properly against the depredations of hares 

 and rabbits. The carrot, besides, requires a deep and mellow 

 soil. When boiled with milk and barley-meal, carrots are 

 said to form excellent food for packs of hunting-dogs. The 

 white Belgian carrot is now established as the best for field- 

 crops.
