slopingly. These "wliips," as they are called, should be covered 

 with earth, like Potatoes in a clamp, till spring, when they should be 

 ]~)lanted out in rows 18 inches by 2 feet apart, the tips just level with 

 the surface. A number of shoots may sprout at the top of each 

 when growth begins, but they should be thinned to one, or the tops 

 will be weak and crowded. If the soil is thoroughly well cultivated 

 and very fertile, every such whip will develop into a forcing crown 

 by the autumn of the same year.

A system of natural forcing is in vogue in some of the Middlesex 

 market gardens, and those who see the pi'oduce resulting cannot but 

 admire ft. The growers take up, say, the first row of Seakale, leave 

 the second and third, take up the fourth, leave the filth and sixth, 

 and so on. Tliis, of course, provides for a number ol ].airs nt rows 

 with wide all. \ > 1 etwoen. From these alleys the sod is taken and 

 heaped in nd-( 1 foot high over the rows. When growth shows at 

 the surface tlje soil is cleared away, and the produce taken I his 

 system does not give such early beakale as hard artificial forcing,
