these tank-heating clays, that a confined tank does 

 not produce the amount of atmospheric moisture 

 which the old tan beds did ; unless some provision 

 be made for the escape of atmospheric moisture in 

 the sides of the chamber containing the tanks, and 

 which must, to produce an equivalent to the tan bed, 

 be permanently supplied with water. 



When the coiled canes are well rooted, it may per- 

 haps be necessary to remove them from the bottom 

 heat, as few can afford to appropriate a pit or house 

 entirely to them. Now this, if rendered imperative, 

 is a serious matter. The only advice that can be 

 offered under these circumstances is, to do it by in- 

 stalments ; that is to say, begin by raising the pots 

 an inch or two out of the plunging medium. In an- 

 other week they may be placed on the surface, and in 

 a few days after removed to any house which will 

 carry out their forcing process. In such a case, it 

 would be well to let them get rather dry previously to 

 removal from the bottom heat, and to apply liquid 

 manure the moment they are placed in their fresh 

 quarters. Mr. Burns, whose practice is here quoted, 

 sets his pots on moss ; and where atmospheric moisture 

 is somewhat deficient the plan is undoubtedly good. 



We come now to the consideration of those 

 established in pots ; and here the process is rather 

 more simple. These can dispense with the bottom 

 heat if thev have a good volume of root ; although,
