 The spectators were allowed to make actual tests on the ScleroScOpe and and found that where this machine registered 25 hardness on the original metal, it was raised in points of eff ficiency to 105. to 110 hardness after the treatment had been effected.
 Tests have been made in the local factories and 1t was dcmonstrated to the satisfaction of every doubting Thomas. that work could be done with tools hardened by the new method, which could not be effected with the best tool steel manufactured. For ex- ample, Chrome nickel steel, one of the hardest steels known, was drilled through a thickness of one inch, by 6 small number drill, made from an ordinary wire nail after 1t had been treated by the infusion process.
 According to chemists. alloyed steels gre the master steels and vanadium is the master alloy. Up to within very short time ago there was less to be in existance in the world. About four years ago Mir. Alfred J. Thomp- son discovered a rich vanadium de- posit in the Andes of Peru, at an al- titude of over 1I,000 feet. Those who follow the steel and engineering jour accomplishment at the time. The se- cret of the success of the treatment under the Thompson Infusion method, is due to the fact that the master alloy Vanadium) is infused into the low grade steel, bringing it up to state of efficiency hitherto found impossible.
 In an interview with MT. Thompson he had the-following to say about his process:
 The process owned and operated by the Infusion Steel Process Company is one by which the exterior. or any part of the exterior of a piece of Homogeneous low grade iron or steel is transformed into high grade 'tooP' steel, and is particularly valuable in the manufacture of tools (for hand or machine work) machine parts, Sagri- cultural implements, ordnance armor. plate, railroad apparatus, safes, auto- mobile parts, etc.
 The output is of a quality and ser- viceability generally far in advance of those brought about by the present recognized methods and with an enor- nous reduction in cost.
 In most cases where "toOl'' steel, costing up to so Or 90 cents per pound, is now used, and in many places where the cheapest class of "tool'' steel can not De uSe0 because or US pfOnlDlIlVe price. equal or better results can be obtained by manufacturing from cheap steel costing from 2 to 1-2 cents per pound. and after machining, to finished form, applying the Infu- sion Process.
 made from stock costing (with freight and haulage included) 1-2 cents per pound which will do three to four times tle work of the best carbon steel drills on the market.
 Milling cutters made from steel costing cents per pound which are superior to other milling cutters (of the best recognized manufacture) made from steel costing eighty-fve G5c) cents per pound.
 With the Infuslon Steel Process all goods arc made Gmachined, etc.) from the softest kind of steel whereby the time( labor and machine) is reduced by from 40 to 60 per cent, tools are reduced over 90 per cent, Ca very inn pertant item in manufacture.)
 The weight of finished tools is only from 30 to 80 per cent of that of the U4Sinal stock, and the cuttings be- ing practically without value the loss from waste (which costs money to re- move) is enormous. For instance in making one inch twist drills:

 ing 2 3-4 lbs weight of finished drill 1-2 lbs Waste in cutting (chip9 IA lbs Cost of waste steel O soc per

 According to the shape of the pieces ito be treated and their adaptibility to being packed in boxes, one pound q lb) of l. s. P. mixture will treat from four to twelve pounds of steel (finish- ed product.) and up to IS lbs according to the area treated.
 This mixture is used over and over again with different heats of steel and retains some infusion" qualities after being burned for seventy-two T2 hours. Second hand' or third hand" I. s. P. mixture is exceptionally good for treating gears, valves, cams, etc.
 For manufacturing purposes the cost of the fuel is almost negligible It varies according to the temperature maintained and to the duration of the heat" Four or five cents per hour will pay for oil for furnace treating 100 lbs of steel and as the average time of treatment will not exceed five hours, the cost of fuel would be less 1-4c per pound of treated material No technical knowledge or training is necessary for the operation of this process. Any laborer of average intel- 1igence can properly take care of all the work to be done.
 The pieces to be treated are pack ed'' in boxes and after being placed in the furnace, the only attention nec- essary is to regulate the heat until the work is infused to the required depth, when the box is withdraw from
