upon should be in robust health, neither having at any 
time shown symptoms of mildew, and the flowers of both 
sciected from fine and well-formed bunches. The opera- 
tion of fertilizing is also a delicate one, and there is some 
diffienlty in getting the two sorts to bloom at the same 
time - for the exotic will, almost without exception, have 
+o be under glass; and the native, on account of producing 
Lardiness, should be planted outside. A temporary glass 
frame to forward the latter would be of service, and the 
former might be retarded by excluding the light until the 
buds burst, and keeping the head down in a cold house 
The most convenient and certain way is to treat one or 
more plants of the native kinds as advised for pot cultue, 
and, when the plants are strong enough, to introduce them 
into a Cold Grapery early in the season, so as to have 
them in blossom as near as possible to the time of the 
others which are in the same apartment ; and if pen 
be paid to the applying of liquid manure, there 
_ need be any doubt of the fruit lacking pela te: 
When the hardy sort begins to open its flowers, the sta- 
mens should be immediately cut out, and the stigma fer- 
tilized by the pollen from the anthers of the exotic; indeed 
it is necessary, if the greatest surety is intended, that the 
corolla (which fits like a little cap over the parts, and rolls 
‘natural liberation, for the anthers generally burst just pre- 
vious to being exposed; and as they encircle the stigma. 
and are immediately over it, impregnation may have then 
taken place, which will most likely frustrate all hopes; fr 
any hermaphrodite plant, previding all the sexual organe 
are perfect, will be more readily fertilized by its own than 
another’s pollen. While the mother plant is in bloom, care 
maat be taken to keep off iasects. This may be done, by
