Lettuce and Cucumber Culture Under Glass. 



In presenting statistics relative to the culture of lettuce 

 and cucumbers under glass, it should be stated that our 

 facilities for collectino- information of this character are not 

 of the best, and consequently the work done by us in this 

 line is not as complete as we Avould wish, but it is believed 

 that the followino; will oive a fairly accurate idea of the 

 extent and importance of this branch of agriculture. 



Our inquiries were extended to the culture in regular 

 greenhouses, sash-houses and hot-bed sash, which hitter are 

 usually six feet by three in size. It was found that the 

 culture varied with the locality and with different individuals 

 in the same locality, and that the price received for the 

 products varied with the quality, season of the year, state 

 of the market, and the favorableness of the season to out- 

 door culture. 



Lettuce is generally considered a hard crop to grow, and 

 it requires much care. It does best on new soil and in new 

 houses. After growing lettuce for several years it is found 

 advisable to discontinue its culture for two or three sea- 

 sons. Lettuce is affected l)y mildew, especially in old 

 houses, in sash-houses and under sash. It is sometimes 

 overcome by putting sulphur on the heating pi[)es, and 

 allowing the fumes to prevade the house ; sometimes by 

 allowing the temperature in the house to fall to 32° F., and 

 remain so over night; sometimes by steaming the house, 

 and then thoroughly airing it ; and sometimes the lower 

 leaves of the plants are picked off, and the rest allowed to 

 head. Tobacco smoke is generally used to destroy lice on 

 lettuce, and sometimes the tobacco stems are steamed, and 

 the vapor used. It is said that tobacco water will spot 

 lettuce if it comes in contact with the leaves. The lettuce 

 season under glass is from September to May. 



The cucumber season in houses is practically the 

 whole year round, and under sash from March to July. 

 Under the best culture, in houses, seventy-two days elapse 

 between the setting out of the cucumber plants and the 

 picking of the cucumbers. Wheii cucumbers are grown
