NOTES OF OBSERVATIONS 
and a dressing of soot and lime was found beneficial for keeping them 
in check. In my own garden, near Isleworth, I found great benefit 
from sprinkling the Cabbages with gas-lime from a heap that had lain 
for about four months exposed to atmospheric action. The weight of 
the finely crumbled material carried it down, and lodged it in the 
crannies of the hearted Cabbages, and made any traffic about the 
Cabbage so unpleasant to the Caterpillars as apparently to check any 
attack from additional ones crawling up the stem. I also sprinkled it 
liberally round the Cabbages, and, though it was not in all cases a 
complete preventive, it did much good. The gas-lime at this stage of 
exposure to the air in no way injured the leafage, and it acted well as 
a preventive of attack from Slugs as well as Caterpillars,

Scarcely noticed. 
14. Phyllotreta undulata. Turnip Fly. Mr. Malcolm Dunn, 
Dalkeith, mentions that the practice of using the water-cart for 
watering Turnips affected by the Fly has been common in the Lotliians 
for a good many years, wherever water is conveniently attainable. 
During the present season (1880) he had seen several water-carts in 
use where the Turnip Fly was troublesome, and the ground hard and 
dry. In the case of a field of Turnips about two miles east of Edin¬ 
burgh, that would not start till the water-cart was resorted to, the 
Turnips were afterwards as fine as any in the district. Mr. A. 
Shearer notes that at Yester, East Lothian, the Turnip Fly did little 
or no harm this year. June was a dry month, but nearly five inches 
of rain fell in July, this being much above the average rainfall. At 
Marchmont, Berwickshire, Mr. Loney mentions the Turnip Fly as 
scarce, and since the rains of September the Turnip crop increased 
immensely in value. Mr. Service mentions that the Fly occurred at 
Maxwelltown, Dumfries, during the first ten days of June, but in few 
instances to any injurious extent. The beginning of June was dry, 
and rain coming on was unfavourable to the increase of the Fly. Mr. 
Service observes that guano is sometimes applied in the district, with 
a view of forcing on the plants beyond the reach of the Fly. Turnip 
Fly is mentioned by Mr. Simpson as having proved very troublesome 
on some farms near Dingwall, Boss-sliire, especially along the shel¬ 
tered sides of the fields. Be-sowing was contemplated in some cases, 
when showery weather set in and saved the plants, at the same time 
that it cleared the Fly. At Poltallock, in Argyllshire, the Turnip Fly 
is noted by Mr. Bussell as rather destructive amongst the first and 
second sowing of Turnips, and a dusting of lime and soot is noted as 
having been found serviceable in destroying the insects. The Fly is
