aged. As stated elsewhere, the grape vine is a plant of 
great longevity ; notwithstanding which, with the prac- 
tice of some vignercns, it is considered to be worn out in 
a few years, and fresh plantations have to be made — 
ically. This may in vineyard culture answer the particu- 
"Yar purposes of the cultivator, and by the method of ae 
allowing a few feet of bearing surface to each individual, 
a great amount of fruit, and suitable quality for his pur- 
pose, may be obtained from a limited extent of land em- 
ployed. Here is evidence that too much cu-tailing of 
the plant’s natural disposition shortens life, am weakens 
down the constitution to such an extent as to make it 
worthless, comparatively speaking, in a very short time. 
Considering that there is not avery great expense in 
replanting a ccna: the means may be said to justify 
the end, but when we come to the catia incurred in 
erecting glass houses, preparing borders, &c., it behooves 
us to think well how we can pay back a permanent inte 
rest on the capital invested, and if there be any method 
that will keep a house of vines in healthy bearing for a 
long time without the requirement of renewal, surely it 
must be wisdom to adoptit. If the grape vine is a long 
liver when allowed to extend, and soon worn out if kept 
leaves, in order the better to concentrate and store up the 
food for future development, and add each year a fresh 
layer of well organized alburnum to the previously exist- 
ingsound vascular tissue? If we take further into account
