their presence is detected the house should be filled with 

 tobacco smoke. This should be repeated everyv two or 

 three days and, if properly done, the aphides will be 

 destroyed. But if they are left until they are developed 

 the tobacco smoke does not seem to be powerful enough, 

 and other means have to be taken. When given proper con- 

 ditions the beds planted the first of October can be cut for 

 Thanksgiving purposes. The next crop will develop by the 

 first of February, and the third crop will be off by the first 

 of April. Under especially favorable conditions two or 

 three weeks can be gained upon this which will allow a 

 fourth crop to be taken off by the middle of April. About 

 two months should be allowed for growing the plants after 

 sowing the seed, and seven or eight weeks more for the 

 growth of the heads after planting out. This will be none 

 too much during the cloudy and short days of November 

 and December, but as the sun gets higher in February and 

 March six weeks will generally suffice. 



LETTUCE IN HOT BEDS. 



When one has a forcing house or can afford to build 

 one, it does not pay to grow lettuce in hot beds in this 

 locality earlier than the fifteenth of February or the 

 first of March. If one has no forcing house or other place 

 for starting the plants, a small hot bed can be made for 

 growing them as early as the middle of January, and tliey 

 will be large enough to transplant by the middle of Feb- 

 ruary. If they are put in thickly at first, a large number 

 of plants can be started in a small bed, and besides saving 

 labor in the care of the large beds, it will admit of giving 

 the plants a fresh bed when finally transplanted. Hot beds 

 can be used to good advantage in connection with a green 

 house, as seed planted about the first pf February will form 

 plants large enough to place in the hot beds by the 15th 

 to the 25th of February and will be ready for market as
