' m ' Oamaro AGulCuXTtma Snow - 'n, Oamaru correspondent of the Timan H„„n writing on July 30, says :—With reference the next show of our Agricultural in. Pastoral Association, it is complicated 7 n the present occasion by the propose! estah lishment of a ram show. The ti m ,. ,'. the Pastoral Show used to be in October r, November, this, however, is too early for Z ram show, and there appears to be a imJ tion on the part of some to postpone both shows till as late as February. This acairi is open to strong objection,as few'willbe disposed to keep their sheep unshorn so lone as that. Again, the Association feels scarcely warranted in incurring the expense of two shows, at different periods of the year and it still remains to be seen how the difficulty is to be got over, I am of opinion that it;, better to incur a little additional cost than to spoil one of the shows. '' New SrsTEM of F E Ncixo.-The Qntem. land hmes thus speaks of a style of wi re fencing lately introduced by Mr. Fit* a t Pilton, the cost of which is little more than one-third of the ordinary three-railed fence Mr. Fitz has caused to be constructed several pile drivers, about eighteen feet high, with rams weighing 3cwt. By means of one of these he is able to drive one hundred pists a day, with the same number of men as would be required to put in thirty posts in the ordi nary way. The posts are delivered, pointed and bored, at such a rate as enabled him to erect the fence at a cost, including wire and labour, of less than £42 per mile, and by a simple contrivance, consisting principally of a roller, he is able to dispense with those costly iron standards which are ordinarily used to stretch the wire, and which may be seen on our railway line. Mr. Wilcox having heard of Mr. Fitz's invention, is about to employ it on the railway.
