VEGETABLES RAISED FOR MARKET 



in the spring, a sowing of the black-seeded variety 

 is made in the open ground ; the rows being spaced 

 one foot apart, and every other row being left 

 out so that celery may be set in later. When the 

 plants are large enough, they are thinned so as 

 to stand one foot apart in the row. 



Sowings are made in this way every ten days 

 until about the twentieth of August. These sow- 

 ings, taken with those made under glass, as 

 described, give continuously maturing crops of 

 lettuce the year round. 



Boston Curled is a very early curled sort, used 

 extensively for first early out-door crops. 



Early Curled Simpson is another excellent 

 curled variety, pale green in colour. It does 

 not form very compact heads. Hanson is one 

 of the leading "head" lettuces for house, garden 

 and other out-door culture. 



The name "Cos" applied to lettuce denotes 

 a class of plants distinguished by the formation

 to head a defect remedied by the art of the 

 grower, who gathers these leaves together and 

 binds them into a compact bunch or head; when 

 they blanch and grow tender, thus becoming fit
