_ We are not without remedy for varieties that have partially 
decayed in a certain‘district. If the trees have once been pro- 
ductive of excellent fruit, and are still in a sounc condition, 
though enfeebled, a thorough renewal of their powers will 
again restore them to health. To effect this, the soil about the 
roots should be replaced by new, enriched by manure or peat- 
compost, and mixed with the mineral substances named in the 
preceding page. The bark of the trunk and large branches 
should be well scraped, and, 4s well as all the limbs, thoroughly 
washed with soft soap. The head should be moderately pruned; 
and finally, the tree should be suffered to bear ‘no fruit for the 
two following seasons. After this it will generally bear excel- 
lent fruit for several years again.t : 2" 
In making plantations of fine old varieties, in districts where 
the stock has become feeble, something may be gained by pro- 
curing grafts or trees from more favourable localities, where the 
fruit is still as fair as ever—and care should be exercised in se- 
lecting only the healthiest grafts or trees. Nurserymen in un- 
favourable districts should endeavour to propagate only from 
trees of healthy character; and if those in their own vicinity 
are diseased, they should spare no pains to bring into their 
nurseries, and propagate only such as they feel confident are 
healthy and sound. - On them, next to the soil, depends very - 
considerably the vigour or debility of the stock of any given va- 
riety in the country around them. : im 
In Mr, Knight’s original essay on the decay of varieties, he 
clearly stated a circumstance that most strongly proves what 
we have here endeavoured to show—viz.: that the local decline 
of a variety is maitly owing to neglect, and to grafting on bad 
* We do not deny that in any given soil there is a period at which a 
variety of tree or plant exhibits most vigour, and after having grown there 
awhile it ceases to have its former luxuriance. The same is true of wheat 
or potatoes, and accordingly farmers are in the habit of “changing their 
seed.” The nutriment for a given variety is after a time exhausted from 
the soil, and unless it is again supplied the tree must decline. In light 
soils this speedily happens. In strong, clayey or rocky soils, the natura) 
decomposition of which affords a continual store ef lime, potash, &c., the 
necessary supply of inorganic food is maintained, and the variety conti 
nues nealthy and productive. 
+ It is not uncommon to hear it said that the Newtown pippin—that 
finest of all apples—is degenerating rapidly.. The solutiun of this is easy. 
More than any other apple does this one need lime and h‘gh culture. In 
proof, we may state that never have there been finer Newtown pippins 
raised, or in so large quantities, as at the present moment on the Hudson 
River. One gentleman's orchards supply hundreds, we may say thousands 
of barrels to the London markets of the fairest, largest, and highest-fla- 
voured fruit we have had the pleasure of seeing or tasting. If any one 
will turn to page 62, he will-speedily see wiz this var ety has net fallen 
into docay at Pelham farm. .
