to budding as practised by Mr. Nairn, a very ingenious 

 man and an excellent practical gardener. This mode 

 is far easier than either inarching or common graft- 

 ing, and therefore deserves the particular attention 

 of the amateur. Mr. Nairn applied it to orange trees, 

 and gives the following directions : — ^ Let the opera- 

 tor select as many orange or lemon stocks as he 

 wishes to work, and place them on a moderate hot- 

 bed for a fortnight, by which time the sap will have 

 risen sufficiently to move the bark : the stocks must 

 then be cut off about two inches above the surface of 

 the pot^ and an incision made with a sharp knife 

 similar to what is done for budding, separating the 

 bark from the wood on each side. Let the scion be 

 cut thin in a sloping direction, and thrust between 

 the bark and wood, and then bound tight with woollen 

 yarn ; but very great care must be taken in binding, 

 to prevent the bark from slipping round the stock, 

 which without attention it is very apt to do. After 

 it is properly and neatly bound, put a little loam or 

 clay close round the stock to the surface of the pot, 

 then cover with a cap-glass. This cap-glass or re- 

 ceiver must be of a form bellied out a little towards 

 the top, and with the top more acute than is usual, 

 in order that the condensed damp that will collect on 

 it may run down its sides, and not drop down from 

 the roof on the scion. The glass must be pressed 

 firmly into the mould to prevent the air or steam from 

 getting to the plant, and must not be taken off unless
