 makes no difference what form is used, provided that care 

 is taken that a complete junction is made on at least one 

 side ; if on both sides, all the better. After the graft 

 has been placed on the stock, it is carefully tied up with 

 Raffia, so as to exclude the air and keep the graft in 

 place. Some prefer to cover the tie with grafting- wax, 

 but that is not indispensable.

sixty to seventy degrees at night, with ten degrees higher 

 during the day, but it is absolutely indispensable to suc- 

 cess that the pots should be so plunged that a bottom 

 heat of at least five degrees higher than the air of the 

 house can be given. This must be done, or there will 

 not be complete success. This bottom heat can be se- 

 cured either by the hot water pipes, or by the ordinary 

 hot-bed, or by using a foot or so of hot manure placed on 

 the benches in the greenhouse ; we ourselves use the latter 

 plan, enclosing the manure by sashes, so as to exclude the 

 air until the grafts have " taken." That plants can bo
