Through damp and cloudy weather the plants are 

 liable to mildew, both in the houses and in frames. 

 Although not as troublesome as insects, mildew often 

 destroys a crop. This can be avoided by keeping up as 

 high a temperature as possible, while still giving plenty 

 of air. In transplanting lettuce, the plants should at 

 first be put four inches apart ; and when they have 

 covered the ground should be moved to eight inches 

 apart in the houses. 



In hot-beds, 50 plants are put under each 3x6 sash, 

 which makes the distances separating the plants about 

 seven and a half inches each way. 



The price for lettuce, through the winter, averages 

 about four cents per single head, or fifty cents per 

 dozen. Three crops can be grown in the hot-houses 

 during the winter. Three can be taken from the hot- 

 beds also, if the plants are started in the houses and 

 grown there until the last transplanting. 



The temperature in the houses should be kept be- 

 tween 40° and 45° in the night time, and at from 60° 

 to 70"* during the day. That of the hot-beds also 

 should be regulated in a similar manner. 



In this vicinity the White Seeded Tennis-ball is 

 almost exclusively the variety raised for forcing ; and 

 the Black Seeded is selected for out-door culture, the 

 latter being very much larger than the former. 



As we have remarked, the first sowing of White 

 Seeded Tennis-ball is made about the first of Septem- 

 ber. The Black Seeded is first sown in February, in 

 the houses, and then transplanted to hot-beds. After 

 being hardened off, it is set in the open ground about
