planting of seed, the method of culture is essentially the same as 

 for leaf lettuce (see p. 99) except that the individual plants require 

 more space. They should be thinned to a foot apart in the row. 

 This should be done early, while the plants are still very small, 

 and before they have a chance to become stunted by reason of 

 crowding.

COS LETTUCE 



There is another type of lettuce somewhat midway in structure 

 between leaf and head lettuce. This is known as cos lettuce or 

 romaine (Fig. 67). The leaves grow erect and are tied together 

 at the top, to induce blanching of the inner parts. In some varie- 

 ties the outer leaves close over the top, so that tying is unnecessary. 

 The cultural requirements of the crop are essentially the same as 

 those of head lettuce. 



EARLY CABBAGE 



Early cabbage is of two general types, the conical-headed and 

 the round-headed (Figs. 68 and 69). Until recently, the very 

 earliest varieties were of the former type, but now there are also 

 round-headed sorts that are extremely early. Both types demand 

 the same kind of culture. 



Since cabbage thrives best when the weather is comparatively 

 cool, though it will stand somewhat more heat than will head
