in illumination, radium in medicine, Monel-metal where tensile strength 
and non-corrosive qualities are required, antimony in type metal and 
shrapnel lead, arsenic in agriculture, the copper-tin-lead-antimony alloys 
for anti-friction metal, alloys of nickel and ¢hromium ‘as resistant 
- substances in electrical work, all have been developed by the persistent 
effort of experimental research, mostly during the last two decades. 
The utilization of products of non-metallic minerals has not kept pace 
with their associates in the mining field. This may be because the 
latter have offered a greater promise of success to the investigator. The 
American Institute of Mining and Metallurgical Engineers is giving 
attention to this matter, and, as a first step, has undertaken to collect 
and disseminate information amongst possible producers and consumers. 
LOW-TEMPERATURE CARBONIZATION. 
Speaking at a meeting of shareholders, the chairman of Low-tem- 
perature Carbonization Limited stated that a contract had now been 
arranged with an electric’ power company in Yorkshire to erect a 
plant and supply all the gas that could be made from the carbonization 
of 500 tons of coal per day. This gas is to be burnt in the power 
company’s boilers in place of raw coal, and since the electric company 
in question is one of the foremost in the country and supplies its 
electric power at a very low rate, the Carbonization Company are 
offering to supply them with gas at a price which shows a great saving 
over coal. aa 
Negotiations have been begun with an influential group of manu- 
facturers situated in a great industrial district in Scotland, the object 
being to provide enormous quantities of power gas for burning under 
boilers in place of coal. -Assurances have been given that consumers 
whose aggregate consumption is 4,000 to 5,000 tons of coal per week 
will purchase gas from a super-carbonizing station operated on the 
company’s process as soon as erected. 
Negotiations are also practically complete for the erection of a 
plant to carbonize a minimum of 500 tons of coal per day near Sheffield.
