NEW ZEALAND'S MAN POWER.

UEPJ.ACED BY A Til ACTOR

'•It" wo can got tractor which wl ' l enable us to grow wheat at ' 11L ' price Mr Ma-M-y -ays wo iiia-t -row it at o.s 1 I'd—then we will welcome it. >«iid j Mr (leorgo Slieat at Bun-imdol on Thursday. "We know we can't grow at that price with hoi>>e traction, so it this machine can enable us to do »<• at. that cost or a hit Ics*. then it is tie tiling for us, for we are patriotic, and want to help to win the war a- best ne can.'' "This machine"' to which Mr Slieat referred was tho - Avery Bulldog Keioseno Tractor'" which had just given an exhibition of how to work a plough in almost impossible .soil, ''hi; '"A^erv 1. new to thi> country, and it ™ "7 11 ' 1 a view to .showing what it could do that the test was held. J*or the experiment, easily the toughest piwldock in the ctlstrict had been selected. Ju iact it wasone which Mr Shcat had used as a hoir-o paddock for 13 years, a nd during all that time it had never been ploughed. In fact one might .just as easily hnvo set a plough to turn up the asphaltcovered thoroughfare of oreester street. There was a very largo gathering of fanner- from the round about district to see the test, and all were agreed thai, five -horses ;U least would have been necessary to drag a double-furrow plough through the ground, and even then the job would have been far front satisfactory. Not so. however, with the "Avei'y.'" r l o tho tractor hitched a " four-furrow plough. The driver set the tractor going, pulled a. string which let flown the .shares, and the I'e-t was as easy as shelling peas. Away went the tractor, and the plough hi';. deep into the soil, and turned it I over as though softer ground had never been attempted. Up and down the paddock went the contrivance, and in its wake lay the well ploughed, well tumed-<>vor soil. The exhibition certainly came as a revelation to all who saw it. Only one man was necessary lor tlu; job, for from the cab of the tractor he could control both the engine and the plougtt trailing behind. The "Avcrv llulldog Tractor appears to represent the acme of tractor perfection. There are nine units in every tractor —the motor, fuel sj'stem, Ignition system, oiling system, cooling system, clutch, transmission, frame, and wheels —and each of these is perfected in the "Avery." Tho Avery Opposed Motor lends itself most successfully in its shape and construction to the requirements of tractor purposes, ajid in it are combined the two necessary features of a successful tractor, narrow width and r all straight spur gear transmission. No owner has ever broken one of the "Avery's" crank shafts. The motors have renewable inner cylinder walls. They run at low speeds, only from 000 to 6.10 revolutions per minute, and low speed means less wear, easier lubrication, greater economy, and require less gears in the transmission. All Avery motors are of tho "valve in the head" type, the most powerful and economical type of all. Their connecting rods are of the strongest possible type, and moreover the entire cam case can be quickly removed by taking off a few nuts. All these facts are the reasons for the unusual success of the Avery Tractor Motors.

The Avery fuel system is- in itself a wonderful invention; consisting as it does of a double carburettor, duplex gasifier, and auxiliary air inlet fuel system, and they get as much out of a, gallon of ordinarv Kerosene as the old style so-culled "Kerosene burning" tractors get out of a gallon of gasoline. AH Avery tractors are equipped, with do-üble carburettors, one bowl for gasoline and the other for- kerosene. The motor starts on the former, and a pull of the lever instantaneously switches over t-o Kerosene. Between the carburettor, and the cylinder is the duplex gasifier, which takes the mixture of kerosene and air as it comes from the carburetter, and further reduces the particles of kerosene, and mixes them with the air in such a way as to form a gas that burns more successfully than kerosene hiis ever been burned, before. The auxiliary air inlet tempers- this gas to the proper degree to geL the most power out of it. The governor on the tractor allows the "Avery" tractors to run at even more uniform speeds than steam engines, while the fuel tanks are so placed as to feed the carburettor by gravity, thus eliminating the necessity of using a fuel pump. The "Avery's" ignition, cooling, oilingi and transmission systems are equally ingenious, economical, and easy to control, while the tractors, because of the sliding frame, have the least gears, the least shafting, . and the least bearings of auv two-speed doubledrive tractors built. Only six gears are used in forward travel, and there are only one counter-shaft and five transmission bearings. Tho sliding frame does away with the intermediate gear shafts and bearings. ( All "Avery" tractors have two speeds, and the advantages of having a two-speed tractor with a low speed for ploughing and other work, and a fast one for light work and travelling on the road, needs no discussion to be fully appreciated by anybody. Furthermore, all "Avery" tractors have double drives, eliminating all frame twisting, making it possible to turn short either way, and making for strength and durability for heavy traction work. In fact, the advantages of the "Avery" transmission and frame are almost incalculable. Added to all these desirabilities, the facts that the "Avery" has only one clutch, and that the wheels are cheaper in first cost, longer lived, and require less repairs than any other wheel built, and one must admit that the "Avery" tractor is a thing which can" hardly be surpassed. A study of its design and construction shows that tho combination of its nine units produces nine great results— durability, reliability, simplicity, light weight, power, speed, economy, accessibility, and ease of handling. The famous "tanks," or "land warships." of the British Army, are built on the tractor principle, and as everyone knows, they can go into and over trenches, shell holes, etc., with the greatest ease. An unrehearsed incident at the test of the "Avery" at Xhinsandel, on Thursday, went to show that the "Bull dog" tractor has the same qualifications, on a smaller scale. The driver, in turning at the end of a furrow, went a bit too far. and got his Iront wheels and one back wheel into a big hole in a water-race. With another machine, this would have meant hours of labour to shift, but a quick reversal by the mechanic, and the "Avery" came out as though it were on a flat road. Other exhibitions went to show that piloting an "Avery' is as simple as steering a motor-car.

The "'Averv" is designed on common-sense lines, with all the latent improvements and accessories, and can be used in practically ?q PI T branch, of farm work. The 18-36 h.n. tractor, which was used at the tests at Dunsandel. has already found a buyer, and will in the near future be seen at work near Longbeach, while nineteen are now in Wellington, and a further seventeen will shortly arrive irnni America, so that for a short time, thorc should be plenty on the market. Messrs W. A. McLaren and_ Co.. Ltd., of 108 ,St. Asaph street, C'hristchurch, for whom Mr H. Holland i-> the manager, have just taken over the Canterbury agency for the '•Averv." and will be giving further exitibilious at the coming Ashburton Show* R
