sions oi the, tube are adapted to the uork required, and the tube is lined with quarzite or speoialptael plates and partly filled with fiint pebbles or steel balls. A mill'oi this type is applicable to wet ~or dry grinding and can be arranged to deal with pieces as large as 7- inch cubes. Any desired fineness oi product can be obtained and there are no high-speed parts to cause breakdown. A jaw-type crusher built irom heavy steel cast- ings is supplied ior crushing ores.

How An Alloy la Built.

Alloys are, in general, oi much greater utility in the Artsthan pure metals. and much labor has been expended upon their periec- tion. The first essential to a real- ly scientific handling oi the pro- blem-ne distinct irom the iortuit- ous methods oi trial and error-is a knowiedgaoi the inner structure oi alloys. How~are the atoms oi the constituent metals assembled in tho alloy, and how does their ar- rangement stiect the properties oi ‘the product? One observer aiter another added to the knowledge oi metallurgy until there was a verit- able maze oi (acts-valuable, but lacking in coherence. Mainly ow- ing to the works oi British scient- ists in the investigation oi struc- ture by X-rays it is now known that metals are crystalline in nat- ure, with their atoms arranged ac- cording to a definite "plan. Further research in this direction has re- vealed similar iniormation con- cerning alloys. The atoms compos- ing the alloy are. oi course, iar smaller than anything which can be sun. They are. indeed, the smallest particles into which the in- dividual metals could conceivably be divided. Yet. small as they are,

how these tiny particles are assem- bled. investigations in British lab- oratories have led to the prediction oi results which can be verified, experimentally, thus demonstrst ing the truth oi the premises. Re- sults oi practical value have al- ready sprung irom these research- es and they will continue to do so in increasing numbers," l, Mi I An Aeroplanefi instruments.

Leaving out oi consideration the aeroplane which fiys by itseii--by no means a figment oi the imagin- ation—-the everyday “air liner" car- ries u wealth oi instruments which are designed to give the pilot ac- curate information. and thus to re- duce the possibilities oi accident. The standard equipment oi a Brit- ish neroplanq includes so-called flying instruments, engine instru- ments. and navigation instruments, in addition to wireless and other electrical apparatus. The fiying instruments-—which, by the way, ily only as passeng o-are ior the purpose oi controlling the aero- plane as a moving vehicle. They consist oi an air-speed indicator to show the rate-at which the mach- ine is travelling through the air. levels to check its height above ground. The engine instruments include a. revolution indicator. oil and air pressure gauges, and a the. ometer to measure the tem- perature oi the cooling water. Fore- most among the navigational in- struments there is. oi course, the compass. In addition there are various other special instruments desigred to simpiiiy long distance achievements as that oi a certain flights and to make possible such British machine which has never landcl except at a desired spot.

Measuring Hardness with a Watch

The hardness oi the suriace oi steel tools, gear wheels, and other metal parts is an excellent guide to the quality and condition oi the meiul. This isct is now becoming recognised by manuiacturers and purchasers alike. and there is a wide demand ior a simple but reli- able means oi measuring the sur- lace hardness oi materials. Any device which involves the making oi microscopic measurements or which damages the suriace oi the metal in any way is obviously un- suitable ior everyday use on finish- ed ports. A new instrument now placed on the market by a British firm. niter many years oi experi- ment, consists- oi a bridge-shaped iraine carrying a' curved bubble tube and several adjustable weights; At the crown oi the arch, on the under side, there is a small bail oi ruby or special steel. When this bull is placed on the material. the hardness oi which is to be measured, the instruments swings a pendulum. The time oi swing,

The machine is practically s. seli-pro- pelllni; jib crane, mounted on trucks or caterpillar tracks. The jib curries a cross arm at the end oi which is a bucket armed with teeth of manganese steel. Even a small machine will dig anything irom 40 cubic yards an hour in stiii clay up to 80 cubic yards in sand or loose material. Three machines recently supplied by a British firm, ior use on a. harbor contract abroad, were oi a muc heavier type. The excavation had to he made through heavy rock and the machine supplied weighed 90 tons. Between these extremes

The best method oi "breaking-up" broody liens is to maike a small grassy run. Provide an open shed or coop ior shelter and then as soon as hen goes brobdy place lser in this outside run. Provide plenty oi water, shell. grit, charcoal, greens and laying mash. Never starve a broody hen since that en- courages broodiness. A coop with a slatted bottom raised ofi the floor or ground and -provided with a ieed trough and. watering cup will also do. The sooner a broody hen is taken away irom the rest and put on a. special diet oi laying mash and green iced. the less time she will lose irom laying.
