THE TURNIP-FLY. 
Roses in Pots, if placed in the forcing house, will produce flowers 
about Christmas. 
Ipomopsis, Isotama, and other handsome annuals, may still be 
sown in pots to flower the following May and June. 
Primula preenitens .—May he propagated by cuttings in the be¬ 
ginning of the month. Take them off a little above the surface of 
the soil, and with a sharp knife cut off the bottom leaves, but by no 
means disturb the upper ones; plant them singly in small pots filled 
with equal parts of loam, peat, and rotten dung. 
Tigridia pavonia, growing in the open borders, must now be 
taken up.

ARTICLE X.—REPORT OF THE COMMITTEE OF THE DONCASTER 
AGRICULTURAL ASSOCIATION ON THE TURNIP-FLY, 
AND TIIE MEANS OF ITS PREVENTION. 
Founded on Returns received to the Questions of the Committee from 102 Corres¬ 
pondents in different parts of England and Scotland. —8 vo. Pamphlet,

The turnip crop, amidst all the improvements of Agriculture, has be¬ 
come of increased importance to the Farmer. As the first step in 
the course of cropping upon all light lands, the after crops in the 
same course are mainly dependant upon its success. If it succeeds, 
the eating off of the turnips, manures, and prepares the land for the 
barley crop, and succeeding seeds; whereas, should it fail, the chief 
support of the barley, and succeeding crop fails with it. Any injury 
therefore to the turnip crop, affects most seriously, the general course 
of management, and no pains or attention, should he spared to pre¬ 
vent it. 
The insect, which is generally known by the name of the turnip 
fly, is one of the most formidable enemies which can attack a crop. 
As soon as the turnip plant appears above ground in its first and 
weakest state of growth, the insect fastens upon it. A few wounds 
from the smallest insect is then, too often, fatal to the plant; and the 
farmer may lose his season for a second sowing, whilst, doubting 
whether the first will sufficiently escape; or may encounter the same 
risk on a second sowing, by ploughing up the first, and bringing his 
land into a state less favourable for its general growth. If the young 
plant be finally destroyed, some less profitable substitute for that crop 
must be sought for, and the labour and expence of preparation for 
turnips is thrown away.
