CALIFORNIAN THISTLES.

I To. the Editor of the "Timaru Herald." J : Sir,—Our friend "Koradi" is "behind the .tinids . on clearing Californians. Where the plough cannot follow them they are all' that he says,—almost hopeless.. But on arable land they can be cleared more easily and cheaply than: such /weeds as twitch and yarrow Plough".'the. patches three inches deep I in January; four inches deep in February, five inches in March, and six ini cites in April, and they will never be 1 heard of again. Nothing must be alloyed to interfere with the four repular. ploughings—not even harvest, : which is the great danger, and no life ! must exist in the soil during the four I months.' To yield to the temptation ito recoup expenses by putting in a ' catch crop of rape where a larger area is treated' means certain failure. The ' cleaning 'of patches can only be done ! well and conveniently while the padI dock; ,is in grass. The discs may be used between the early but not as a"substitute for the ploughings. .—I am, etc., | ' ' D. F. PLOUGH.
