scufflers to level down the earth ; then the field wo)kers with hoes 
to uncover the blades or leaves of tlio turnips. When uncovered, 
the leaves that had been buried showed the caterpillars upon them 
quite HveJy, when I expected they would have been dead." — J. G. 
"Good black land in ffood heart is free from attack. Heavy clay 
land is destroyed a good l)it, especially where it is of a wet nature. 
Light mossy land with a little gravel through it is entirely destroyed ; 
nothing left but a few stumps. Manure used : about 20 square yard.s 
of good farmyard dung with about 10 cwt. manure, composed of three 
parts dissolved bones, tliree superphosphate, three sulphate of potash, 
and one nitrate of soda ; the land was heavily ploughed." — J. H. 
The land on which the turnips are worst is generally stiff but not 
always, and those fields which are destroyed are generally those 
which are not in a thriving state when they are attacked. The 
depth at which the land in Fife is ploughed in stubble is from G to 
8 inches ; the manure used is generally half dung and some light 
manure. No salt." — J. L. 
" Oolite and on cl.ay, worse on clay ; autumn cultivated and 
ploughed C inches ; 1 cwt. bone dust, 3 cwt. mixeil phosphates." —

" Part red clay, but mostly whinstone gravel ; all the land I liave 
turnip this year (100 acres) lias been limed within tiie last four years 
at the rate of 7 tons shell lime per acre. All my turnips are after 
oats. The land was all ploughed during autumn and early spring 
about 10 inches deep ; it all had two furrows, just before sowing. 
Thirty aci'es of swedes had fifteen loads farmyai-d manure, 5 cwt. 
Thomas's phosphate powder, 2 cwt. kaiiiit, and 1 cwt. nitrate of soda 
put on the ridge and split in just before sowing ; 10 acres had the same 
quantity of farm manure ploughed in during autumn, also the same 
artificial per acre, and the ridges split before the seed was sown. After 
having the caterpillars brushed off, I top-dressed the whole with 
V cwt. nitrate of soda and 2 cwt. salt per acre. Now it is scarcely 
possible to tell anything lias e\er been on them, they are looking so 
well."— W. P. 
" Fine alluvial, deep and lightly ploughed in different parts ; 
superphosphate and salt used."- — C. C. R. 
" Clay loam, previous crop oats, deep ploughed in autumn shortly 
after harvest, crops ploughed end of January and twice afterwards. 
Superphosphate only used, no salt or farmyard dung." — F. R. 
" My land all natural turnip land, some with sand or sandy loams 
and clay loams. First field attacked was twice scarified in the fall 
of 1890 and all stubble and weeds raked off; deeply ploughed 8 
inches in February and again in May and dunged in drills. Where 
rotted dung was applied tiie plants have outlived the attack ; where 
courtyard dung, fresh, the plants all perished." — J. Sn. 
" Fine loam. — In one field I had rather a good instance of culti- 
vation, as out of the field (whicli is about 3 acres) 2 acres were not 
ploughed till just before sowing swedes (the field had been oats) ; 
the rest was ploughed in winter ; the caterpillar was equally bad 
on both bits where swedes were sown, but hardly did any harm to a
