110 MARKET GARDEIS'IKG. 



radishes will amount to about the same as from a third 

 croD of lettuce, which, of course, is always less than the 

 first or second crop. 



A week or two before the last crop of letture is 

 ready for market, hills for cucumbers may be made six 

 to eight feet apart in the beds, and the seeds planted. 

 The lettuce is out of the way long before the cucumbers 

 bedn to run and need room. Cucumbers planted in 

 this manner come into market at the same time others 

 arrive from Florida and Charlestown. The forced cu- 

 cumbers sell freely for twice as much as those coming 

 from the South, being fresh and crisp, while the others 

 are not. When the cucumbers are taken off, the houses 

 are given rest for the balance of the summer, unless the 

 market is such as to warrant those usually less profitable 

 crops, such as asparagus, egg plant, tomatoes, rhubarb,

 effective method of fumigating, is to have a number of 

 small sheet iron cones, from fifteen to eighteen inches 

 high, and eight to ten inches in diameter, each having 

 a grate near the botton, an opening to give draft, and a 

 damper to regulate the draft. In each place a charge of 

 damp tobacco stems and wood shavings, and set them in 

 different parts of the house, igniting all at the same 

 time. This will be found the best and most effectual 

 way to apply the tobacco, using about two pounds of 

 dry tobacco to every one thousand feet of glass. 



Profits from Forcing Houses. — The profits from 

 this branch of market gardening depend largely upon 

 the skill and intelligence of the gardener. The first
