be lour or five feet wide, and as long as desired; 

 of course, covered with glass. If made six feet 

 wide, the ordinary 3x6 glass can be used, which 

 is more convenient; and, in such case, it is desir- 

 able to have box flues leading across through the 

 centre of the bed from one trench to the other in 

 order to promote distribution of the heat. Some- 

 times there is only one trench, running length- 

 wise through the centre of the bed, thus dividing 

 it into two narrow ones. 



The growth made in forcing-houses enclosing 

 temporary beds is thought, however, to be rather 

 more profitable in the final result. It is usual to 

 make the temporary bed three feet wide; and for 

 asparagus the rows are put one foot apart, with the 

 plants eighteen inches apart in the row. Such 

 close planting will need heavy manuring and 

 close attention. 



If a cheap house for forcing asparagus, etc., in 

 early spring is as much as is aimed at, the following 

 plan, recommended in "The American Garden," 

 is as good as any. It may be made either as a

 above ground. Frame and cover with glass. If
