is finished be sure that there are enough handles on it to allow the 
expressmen to handle it with ease. 
Paint Brushes, Care of.— To soften brushes get from your drug- 
gist one pint of benzole, not benzine; stand brushes in it a few minutes, 
then press up and down until soft; wash them first in turpentine, fol- 
lowed by warm water and soap. 
Painting Heating Pipes.— Do not buy the dry lampblack, which 
comes in powder form, but that which is in paste form, and thin it 
with pure linseed oil until it is in paint form. The radiation of heat 
probably will be greater from pipes painted with this lampblack’ paint, 
than from those painted with white paint. Pipes may be made silver 
white, by painting with aluminum paint. 
Petroleum Bmulsion. — Make some moderately strong soapsuds 
and mix 7 oz. of oil with 8 gal. of soapsuds. It readily combines with 
the suds, and can be then applied uniformly with a syringe. It is a 
good thing for aphis, thrips, mealy bug, and may be used in dilution 
suited to the nature of the plants requiring treatment. 
Photographing a Store Window. — It is generally very difficult 
to obtain a clear photograph of a shop window without reflection from 
whatever may be on the opposite side of the street. A successful 
photographer known to us selects a time when the traffic on the street 
is practically ended for the day — 10 or 11 o’clock at night, for instance. 
The ordinary lights are then turned on inside the plate glass window 
and the artist proceeds to take his photograph exactly as he would any 
other subject. The remaining difficulty is the amount of exposure to 
be given, and this each photographer must judge for himself, according 
to the amount of light obtainable, diaphragm used, etc. 
Peach Leaf Curl. — This disease is widely distributed and appears 
in May and June, causing the leaves to curl and usually to be discolored 
with tints of yellow and pink. These leaves fall and the tree produces 
a new crop of foliage, but if the disease is serious it is impossible for 
it to produce a second crop of leaves and a crop of fruit in the same 
season. When the disease reaches this stage it is impossible to do any- 
thing for its control. The trees must be sprayed with Bordeaux mix- 
ure before the buds open if the leaf curl is to be controlled. 
Poison Ivy will not be killed by a single cutting, as new shoots 
or suckers are persistently sent up from the rootstocks. The rootstocks 
must be exhausted by destroying the foliage as fast as it appears, either 
by repeated mowing or by spraying with a strong salt brine made at 
the rate of three pounds of common salt per gallon of water. If the 
weed is cut or sprayed in June and the treatment repeated about three 
times at intervals of 10 days or two weeks, the rootstocks will become 
exhausted and die. Arsenate of soda (a violent poison), Vi pound per 
gallon of water, or crude oil may be substituted for the salt spray. 
Spraying does not affect the roots directly, but is simply equivalent to 
cutting. However, there is the advantage that one need not come into 
actual contact with the plant. 
Pot-herbs. — Wild plants used as pot-herbs are Curly Dock, Pig- 
weed or Lamb’s Quarters, Chickweed, Mustard shoots, purple Milkweed
