grown they are transplanted, being set four in a hill ; 

 and thirty-two hills being put under each 3x6 sash. 

 They are left to grow in this manner until they are 

 about four inches high Cwhich usually takes about four 

 weeks from the time of sowing). They are then re- 

 moved ; and each hill is placed under a 3 x 6 sash, and 

 given good, steady heat, such as keeps the ground and 

 roots thoroughly warm. The bed should be kept at 

 an average temperature of about 70°, corresponding to 

 ordinary midsummer weather. The requisite heat is 

 afforded by the heating material that has been placed 

 underneath, aided by the sun, and is retained at night 

 by covering with mats and shutters. It is regulated 

 by means of a thermom&ter, and ought not to run 

 lower than 50° at night, or higher than 90° during the 

 day. In case the thermometer rises higher than this, 

 the beds should be cooled by raising the sash. The 

 vines are sometimes grown in lettuce beds, after the 

 lettuce has been removed, by putting in fresh heating 

 material, but it is much better, when practicable, to 

 make a fresh bed. The plants, after being established, 

 should be reduced to three in a hill, as it is no ad- 

 vantage, but a drawback, to have too much vine. They 

 require the .same care under glass that they would re- 

 ceive in field culture. Especially under glass they are 

 a very quick growing crop, and will require picking as 

 often as four times a week. The picking may ordina- 

 rily be commenced about June ist ; and about this 

 time the glass should be removed from the bed. Those 

 gathered in the earliest pickings usually bring about 

 ten cents each ; of course as the season advances
