for this latitude. The after culture is well 
known. 
Now, in any ordinary season an acre of 
tomato plants treated in this way ought to 
produce, between June 20tli and July 10th, 
(which last is about the date the first Anne 
Arundel tomatoes usually appear in Balti¬ 
more,) at least fifteen bushels of fine to¬ 
matoes (I have had over twenty bushels in 
the same time.) For several years past the 
first Anne Arundel tomatoes have brought 
five dollars a box. Last year they brought 
five dollars a box up to the middle of July. 
So the additional twenty days will give us 
at least seventy-five dollars an acre. Now, 
a greenhouse such as I have decribed will 
accommodate plants for four acres, and 
have a warm corner to start a box of egg 
plants a while before the tomato plants go 
out. So the advance on four acres of toma¬ 
toes alone will build such a greenhouse in 
one season. 
Two years ago, when I cut down my to¬ 
mato plants, I put the tops into the propa¬ 
gating house and rooted them. Thejr were 
put out into frames at the same time the 
cut-down plants were, and at planting time 
no one could see any difference in size of 
the plants. At ripening time the cut-down 
plants were full three weeks ahead of the 
tops. I have also given friends plants be¬ 
fore they had been cut down, who treated 
them in the usual manner, and yet were 
weeks behind my plants drawn out of the 
same box. 
Roiiiid-He&ded. Apple Tree Borer. 
James W. Robinson, Esq., of Fremont, 
111., an ex-president of the Illinois State 
Horticultural Society, gives the following 
mode of dealing with this destructive in¬ 
sect : The eggs are deposited in the bark of 
the tres, the beetle puncturing or splitting 
the bark of the tree upward or downward 
and a little sidewise, the puncture looking 
very much as if made with an ordinary 
pocket-knife. The eggs are usually inject¬ 
ed into this puncture so deep as to be out of 
sight; but not always. On.young and thin 
barked trees the eggs will be pushed in 
next to the wood, but in older and thicker 
barked trees they will only be through the 
hard outer bark and the inner soft bark. 
As soon as the egg begins to hatch, which 
is in a few days after, being deposited, its 
enlargement causes the puncture to open, 
and thereby it is much easier detected. 
The young borer hatches out in the inner 
side of the egg and eats out a circular piece 
the size of a half dime; and then starts ofl'„ 
boring upward at first, but sometimes side- 
wise or downward. At this state of devel¬ 
opment it is easy to detect the young depre¬ 
dator by a few drops of discolored juice of 
the tree extending from the puncture and* 
sticking on the bark. The larvae usually 
bore down below the ground surface in 
winter, and up again in summer, living in 
the larvae state in the tree nearly two years 
then boring out in the form of the beetle, 
ready to repeat their round again. The 
remedy I have successfully used is to keep 
the ground around the trunks of the trees 
clean and mellow, so that there will be no 
cracks or openings there for beetles to get 
in to lay their eggs in the tree, and so that 
the puncture where the eggs are laid or 
young beetles hatching may be easily seen, 
and eggs or insects destroyed, which can 
be done while in the eggs by merely press¬ 
ing firmly on the puncture with a knife 
blade (the cracking of the egg can be heard 
distinctly,) and if hatched, by cutting away 
the dead bark over the little cavity first 
eaten out, and killling the young worm. 
The borers do not go into the wood much 
the first year, and can be easily followed 
with the knife; but if not taken out soon 
after hatching, they seriously injureif not 
entirely kill the tree, especially when they 
run around under the bark, as they some¬ 
times do. Or, when several borers are in a 
small tree, they so injured it that it breaks 
over with the wind. If the ground is well 
cleared and patted down smooth around the 
trees about the last of June, the destroying 
of the eggs and young borers will be more 
certain. The trees should be examined 
twice or three times a year, if the borers 
are very numerous, in order that the first 
hatched may be killed before they do seri¬ 
ous injury to the trees. August. Septem- 
ber and October are the months in which to
