THE PEACH. 
proved that if a small quantity, say half a peclc of air-slaked 
lime, is heapec. around the trunk of each tree at the end of May 
and suffered to remain till October, the peach-borer will not at- 
tack it. It has been tried most successfully in large orchards, 
where the protected trees have long remained sound, while 
those unprotected have been speedily destroyed by the borer. 
The remedy undoubtedly lies chiefly in covering the most vul- 
nerable portion of the tree from the attack of the insect ; and 
therefore persons have been more or less successful with ashe^ 
charcoal, clay, mortar, and other protectives. But we recom- 
mend for this purpose air-slaked lime or ashes* because these 
more fully answer the purpose as protectives, and when spread 
over the surface, as they should be every autumn, they form the 
best fertilizers for the peach tree. 
This is the easiest and the most successful mode, and it 
should not be neglected a single season. Many careful and 
rigid cultivators prefer a regular examination of the trees every 
fpring and autumn. On removing the earth, for a few inches, 
fhe appearance of gum or castings quickly indicates where the 
borer has made his lodging. A few motnents with the knife 
will then eradicate the insect for the season. This is a very 
effectual mode, but not, on the whole, so simple or so good as 
the other, because the tree is always left exposed to attack, and 
to consequent injury, before the insect is dislodged. 
The Yellows. This most serious malady seems to belong 
exclusively to this country, and to attack only the peach tree. 
Although it has been the greatest enemy of the peach planter 
for the last thirty years — rendering the life of the tree uncer- 
tain, and frequently spreading over and destroying the orchards 
of whole districts — still little is known of its nature, and nothing 
with certainty of its cause. Many slight observers have con- 
founded it with the effects of the peach-borer, but all persons 
who have carefully examined it, know r that the two are totally 
distinct. Trees may frequently be attacked by both the yel- 
lows and the borer, but hundreds die of the yellows when the 
most minute inspection of the roots and branches can discover 
no insect or visible cause. Still we believe proper cultivation 
will entirely rid our gardens and orchards of this malady ; an/ 
this belief is in part borne out by experiments under our own 
inspection. In order to combat it successfully, it is necessary 
that the symptoms should be clearly understood. 
Symptoms. The Yellows appears to be a corstitutional dis- 
ease, no external cause having yet been assigned for it. Its in- 
fallible symptoms are the following : 
1. The production upon the branches of very slender , wiry 
shoots , a few inches long, and bearing starved, diminutive leaves. 
* Bleached ashes.
