182 THE FLORAL WORLD AND GARDEN GUIDE. 
This must be done several times in the course of the year, in fact, 
as often as may be necessary. It is so difficult to eradicate mealy 
bug from pine-apples, that stocks infested should be burnt, and after 
the house has been thoroughly cleaned, painted, and whitewashed, 
a new beginning made with suckers obtained from a thoroughly 
clean stock. Grape vines infested with mealy bug must be frequently 
examined when they are in full growth, and the clusters of the 
pest be brushed away. At the winter pruning well wash every 
particle of the wood, and then dress them with a mixture prepared 
as follows:—To ten quarts of water add tobacco one-half pound, 
sulphur one pound, soft-soap one pound, anda table-spoonful of 
spirits of turpentine. To properly mix the several ingredients, boil, 
first of all, the tobacco for twenty minutes in about three quarts of 
water. Then with a little of this water, whilst quite hot, work the 
turpentine, sulphur, and soft-soap, into a paste, and when they have 
been well mixed, gradually pour upon the mixture the remainder of 
the boiling water, and finally add sufficient clear water to make ten 
quarts in all. The vines must be painted all over with this mixture, 
and sufficient care taken to avoid rubbing or in any way injuring 
the buds. Those who may be anxious to avoid the trouble of 
preparing a mixture as here advised can dress the vines with 
Gishurst Compound, prepared at the rate of eight ounces to the 
gallon of water, and sufficient clay added to make it of the con- 
sistency of paint. To amateurs with but little time on their hands, 
the mixture of Gishurst can be strongly recommended. 
Rep Spemwer (Acarus tellarius) is a very troublesome pest, for 
there is hardly a plant cultivated with the aid of glass that is not 
more or less subject to its attacks. A moist atmosphere is one of 
the best preventives, for so long as the atmosphere of the house is 
moderately moist, and the plants can be syringed once or twice a 
day, it makes very little headway, but immediately these conditions 
are changed it spreads with extreme rapidity. Syringing the plants 
thoroughly is one of the best remedies, and when grape vines become 
infested, the house should be shut up rather early in the afternoon, 
and the vines be thoroughly syringed. This can only be done before 
the grapes begin to colour. The fumes of sulphur are most de- 
structive to red spider, and the hot-water pipes in vineries, cucumber 
houses, or melon pits, to which red spider finds its way, should be 
sprinkled with sulphur occasionally, or be painted with a mixture of 
sulphur and clay. For the first two or three days after the appli- 
cation of sulphur the pipes must not be made so hot that the hand 
cannot be laid upon them with comfort, or the fumes will probably be 
so strong that the tender leaves will be injured. Plants in pots may 
be cleared of red spider by sponging the leaves with water in which 
Gishurst, Compound has been dissolved, at the rate of one and a half 
ounces to the gallon, and in about twelve hours afterwards syringing 
or washing them with perfectly clear water. The sponging should 
commence immediately the pest is detected. 
Scare.—Of these there are several kinds, and all very difficult 
to destroy, because of the impracticability of applying a remedy of 
sufficient strength to destroy them without injuring the plants..
