April 30th, or 44 days from seed. Simpson curled was sown Octo- 

 ber 3d. November 7th, transplanted to bed. It was desired to hold the 

 crop back, so that the house 

 was kept very cold ; and the 

 variety is not well adapted 

 to quick forcing, so that it 

 was January 30th, before 

 the entire crop was fit for 

 market, making 119 days 

 from seed. Grand Rapids 

 lettuce sown December 

 28th; transplanted to bed, 

 January 16th; began mar- 

 keting March 21st. This 

 makes 72 days from seed, 

 in the dark months ; and 

 at least a week could have 

 been gained if we had not 

 been obliged to delay trans- 

 planting whilst waiting for 

 a crop of chrysantnemums 

 to come off the bed. 

 The varieties of forcing let- 

 tuce are many, but the lead- 

 ing ones at present are the 

 Boston Market or White- 

 Seeded Tennis Ball, and 

 Grand Rapids. The for-

 lettuce of eastern markets. 

 It is usually a difficult vari- 

 ety to grow to perfection 

 unless the soil and condi- 

 tions are well adapted to it. 

 Another excellent lettuce 

 of this type is Land re th 

 Forcing, shown two-thirds 

 grown in Fig. 69. The 

 Grand Rapids is a loose- 

 leavedjjettuce, shown full
