44 GARDENING FOE PROFIT. 



valuable matter. In turning under so tall a crop as corn 

 or rye the plow should be run across the rows, and a 

 heavy chain looped from the plow beam, just ahead of 

 the standard, to the land side end of the inner whiffle- 

 tree. This loop drags in the furrow, so as to catch the 

 falling corn or rye, and pulls it down and into the fur- 

 row so that the soil covers it. It should then be smoothed 

 down with the back of the ordinary harrow or by the 

 shortened blades of the Acme Harrow, so as to fill up the 

 crevices, and thus quickly induce the rotting of the green 

 crop. 



CHAPTER VII. 

 THE USE AND MANAGEMENT OF COLD FRAMES. 



We use cold frames for preserving Cauliflower, Cab- 

 bage and Lettuce plants during the winter, and the for- 

 warding of Lettuce and Cucumbers in spring and summer. 



To make the matter as clear as possible, we will sup- 

 pose that the market gardener, having five or six acres of 

 land, has provided himself with 100 of three by six foot 

 sashes. The Cauliflower, Cabbage, or Lettuce plants, 

 which they are intended to cover in winter, should be 

 sown in the open garden from the 15th to the 20th of 

 September in the latitude of New York ; farther north, 

 earlier ; farther south, later. This matter of time of 

 sowing is of vital importance ; for if too early, many of 

 them will run to seed and of course are useless ; again, 

 if sowing is done too late, cold weather sets in and the 

 plants have not time to get strong enough to stand the 

 winter. The Early Jersey Wakefield is the variety used 

 almost exclusively for raising cold frame plants. Our 

 famous "Early Summer Cabbage" i. never so safe to
