448 Report on the Exhibition and Trial of Implements 



whole of the artieles that we inspected ; it would extend this report to greater 

 length fliau most readers will approve, to say more than a few words on those 

 we selected for honorary distinctions. First then, as to the medals. 



Cottam and Cottam's Iron CoUar-har Hurdles. — Any one who has had much 

 to do with iron fencing must have discovered that the middle standard in the 

 hurdles is constantly shifting. This inisteadiness tends to weaken the fence 

 and spoil its uniform look. Messrs. Cottam have applied a simple and effectual 

 remedy. They have welded a small collar of iron on the bars of the hurdles ; 

 the collars are placed on alternate sides of the standards, which thus become 

 tightly fixed. Tlie iron fencing is thus considerably strengthened without any 

 detraction from its light appearance, and, what is of more consequence, with- 

 out any extra cost to the purchasers. 



Perreaux and Co 's Vulcanised India-ruhher Pump Valve. — We are indebted 

 to M. L. C. Perreaux, of Paris, for tliis clever invention. Liquid manure pumps 

 are constantly out of sorts; the acids of the manure speedily destroying the 

 best leather valve, and the pump often stops from straws or other substances 

 that stick in the valves. It appears probable that vulcanised India-rubber 

 will resist the destructive influence of the manures, and from its flexibility it 

 is impossible to choke it. A small pump in the Salisbury yard readily took 

 up corks, large rags, and other such tilings ; and what is more wonderful, still 

 threw up a steady stream of water. Any description of this invention, without 

 an illustration, would be hard to comprehend, and for further particulars we 

 must refer to the description given in the prize list of the last Journal. 



Messrs. Hill and Smith's ivrouf/Jd- iron Sheep Trour/hwe considered worthy of 

 a medal. It was well and substantially made, yet light and ])ortable, being 

 mounted on four wheels. The sheei) cannot throw out any food, or easily 

 upset the trough, and a rail prevents them jumping over or getting into it. 

 It was 9 feet long, and cost 30s. It would answer well for water in summer, 

 and, with a coat of tar now and then, would last a great number of years. 

 We may here observe that we highly commended a water trough of Mr. 

 Grijiper, and commended the cheap and durable wrought-iron cattle troughs 

 exhibited by Messrs. Burney and Bellamy. 



Mr. Carson, of Warminster, showed a compact and excellent Cheese Press. 

 It was well manufactured, and a great pressure is obtained for large cheeses 

 by the weight being suspended from a compound lever over a pulley ; by this 

 means the simple weight produces a double pressure. The price Avas reason- 

 able, 55s. 



Messrs. Cockey and Sons had a very complete Cheese-making Apparatus. 

 We are not practically acquainted with extensive cheese-making, but heard 

 from some gentlemen who had used the apjiaratus, that a great saving was 

 effected, and better cheese produced. The whole arrangements seemed grounded 

 on scientific and economical principles. 



The only competitive trial in the miscellaneous department was among the 

 churns. Three small churns contested for the medal which we had to award 

 in that class. Each churn was furnished with a little more than 2 quarts of 

 average cream, and the following is the result of the trial : —
