330 Report of the Horticulturist of the 



The method may be briefly outlined as follows : 



The bench, six inches deep, is half filled with well-rotted manure, 

 over which is spread three inches of soil. 



The soil is made of one part by measure of manure to three parts 

 of rotted sod. Should the sod be from a heavy loam it is made 

 lighter by adding one part by measure of sand to three parts of sod. 



The plants are transplanted but once and that is from the seed 

 flats to two inch pots. 



The pots are plunged into the soil on the benches so that the tops 

 are covered with nearly half an inch of soil. 



The distance between the plants on the bench varies with the 

 variety, but is usually ten inches each way. 



Before the pot is plunged in the soil it is turned up side down 

 and the under side of the leaves thoroughly dusted with tobacco to 

 prevent attacks of aphis. The upper side of the leaves is then 

 dusted with tobacco and about a week later the plants are dusted 

 again, being especially careful to apply the t.obacco thoroughly in 

 the tender centres of the growing plants. 



As to the care of lettuce under glass it may be said that : 



The house should be kept at a cool even temperature, running a 

 few degrees above fifty in the day and remaining at fifty or a little 

 below at night. 



Sudden fluctuations from high to low temperature or vice versa 

 should be avoided. 



The plants should have plenty of fresh air especially on sunny 

 days when the temperature is high outside. 



When the plants are watered over head it is best to select a time 

 when the foliage will dry quickly. Avoid watering so late in the 

 day that the plants will not dry before night.
