GRAPE-VINE. 85 
effect, a rule which is applicable to all other plants or trees, 
Hence, the judicious selection and application of manures 
are important matters. Ground bones, horn shavings, old 
woolen rags, the dust and dirt from paved roads and streets, 
perfectly rotted stable manure, poudrette, are some of the 
best. 
To believe that the vine will continue to bear to all 
time, with no other. nourishment than it receives from its 
own refuse, is inconsistent with the revelations of recent 
scientific researches. Organic chemistry shows us what 
the fruit extracts from the soil, among which are large pro- 
portions of phosphate of lime and potash. A portion of 
the last may be restored by the return of the trimmings 
-and leaves. But ultimately the potash required by the 
vine must be exhausted wherever there is not a granitic 
soil to furnish it, by the decomposition of its felspar or 
mica. As to the phosphate of lime taken away with the 
fruit, scarcely any portion of which is returned by the vine- 
wood and leaves, this must be supplied to the vine in some 
form, or otherwise its productiveness must be very limited. 
Management of the Vine under Glass.—The vines may 
be planted either on the inside or outside of the grapery, 
to correspond with the rafters to which they are to be 
trained. When on the outside, 2 bank of earth is to be 
raised over the roots, and the vines brought under the 
outer wall through appropriate notches, 
Training and Pruning.—The main stems are to be cut 
off even with the bottom of the glass, and two shoots al- 
lowed to start from it the first season, and if any fruit ap- 
pears, one bunch may be allowed to grow on the strongest 
shoot.. Train the shoots up the rafters as high as they will 
go, but do not top them when a third or half way up, as 
some have advised. The succeeding winter lay the strong.
