slightly morning and evening at all seasons, except when the weather is 
very wet. About the end of February it will require another shift, and if 
well rooted a pot two sizes larger should be used. One shift annually in 
February will then be sufficient, but always use good fibry peat and sand as 
above recommended for the purpose. The thrips must be looked sharply 
after and kept down, for if once allowed to gain a footing they will soon 
destroy not only the foliage, but the plant also. As soon as blooming is 
over, remove the seed vessels from the stems, in doing which care must be 
taken not to injure the wood, as the young growth continues on from the 
top of the flower spike, the point of which should be taken off above the first 
set of leaves.

THE WINTER DRESSING OF ORCHARD-HOUSE TREES. 
a^iRCHAED-HOUSE trees, &c., maybe kept free from insects by very 
simple means. The method I have adopted since making the 
/(b observations noted at p. 44, is as follows :—As soon as the leaves 
fall, the trees are pruned, and well washed with cold water thrown 
upon them by a powerful engine. This washing is repeated two or 
three times, and it tends to remove dust, and possibly a portion of the 
insect ova, &c., which may have been deposited. The house is thrown 
quite open, and nothing more is done until the buds begin to sw T ell in 
spring, when the engine is again brought into action on the morning of 
every favourable day, the practice being of course discontinued as soon as 
the blossoms begin to expand. 
As soon as the fruit is set, if insects are found to be at all troublesome 
fumigation is resorted to; and it is found that with the aid of two simply 
contrived, but very effective fumigators, using a quarter of a stone of 
tobacco paper which costs 5s., mixed with d lb. tobacco, which costs Is., a 
span-roofed orchard house 80 feet long, 20 feet wide, and 12 feet high, can 
be filled with a dense volume of smoke, which kills everything in the shape 
of thrips, and of green or black fly. This operation is seldom required to be 
performed oftener than twice or thrice during the season. 
With regard to Peach, and other trees trained upon w T alls in the open 
air, I would recommend in all respects similar treatment to that above 
described as adopted for trees in the orchard-house, substituting for the 
fumigation, in the case of the wall trees, a thorough syringing with a solution 
of Gishurst Compound, using about 4 oz. to a gallon of boiling water. This 
syringing, like the fumigation, will not be required to be repeated many 
times during a season. 
The brown scale will sometimes attack the Peach and other trees 
in the orchard-house. When such is found to be the case, they must be
