of others being brought in from outside that have 

 developed since the first lot of plants was lifted. 



Another method of protecting the Lettuces is to 

 place frames over them as they are growing : rough 

 three-light frames are very useful for this purpose. 

 Mats and long stable litter should be used for cover- 

 ing at night, taking care to place plenty of the litter 

 around the sides of the frame. 



During mild weather draw the lights off, tilting 

 them at the back instead when it rains. Ventilate every 

 day when the temperature is above freezing point. 



From a sowing made late in the month of August 

 of both Cabbage and Cos varieties, part of a frame or 

 cold pit may be planted : they will provide excellent 

 Lettuce by April. 



The plants raised from seed in September and put 

 out on a south border should, in January, be planted 

 in a heated pit in soil resting upon a mild hot-bed. 

 These quickly develop into Lettuces of the best quality. 

 Cabbage varieties are best suited for this treatment. 



Plants from a sowing made in January, upon a hot- 

 bed, will succeed the first early crop sown in the autumn. 



Planting. The distance apart at which Lettuces 

 should be planted depends upon what size they attain 

 when fully grown. Small-growing varieties may be 

 planted eight inches distant from each other, those of 

 medium size at ten inches and the larger ones twelve 

 inches apart. 



It is necessary to tie some Cos varieties in order to 

 cause them to blanch, and this should be done a fort-
