SIR HENRY CORT HAROLD CARPENTER, great-great-grandson of Henry Cort, famous as the initiator of iron puddling some 150 years ago, carries on the tradition of an illustrious name. Newest of those elected to the Institute's roster of Honorary Members, Sir Harold is distinguished for his achievements in the field of metallurgy as an investigator, teacher, administrator, organizer, and director of research. His interests in research have been in both the ferrous and non-ferrous fields. His name is particularly honored in its association with the establishment of fundamental con¬stants and of critical ranges of iron and iron alloys, and with original and fundamental studies of the preparation and properties of metal single crystals.

At Asarco's Mission mill. located near Sahuarita, Ariz., the 20 500-t/d (22,500-stpd) throughput of highly abrasive and corrosive copper ore can play havoc on equipment wear parts. To minimize frequent replacement work and extend life on key components, Asarco engineers have over the past five years utilized liners made of "Towniprene" in the secondary grinding and flotation area of the plant. Results to date have indicated that these liners last between three and five times longer than those made of metal or ordinary rubber.

The experience of the Committee in connection with securing papers for the Butte meeting in August has shown that authors should begin early on papers contemplated for the New York meeting next February. So many papers come in at the last moment that it becomes exceedingly difficult to have them all read, indorsed, and delivered to the printer in time. Authors should remember that those serving on this Committee are doing so without pecuniary compensation, and it is hardly fair to expect them to devote so much of their time at the last moment from their private affairs. So many papers have to be sent back for corrections of one kind or another, that it is desirable that they be sent to the Committee at least three months previous to the date of the meeting. The Committee desires to be kept informed of contemplated papers on metallurgical subjects particularly. It is hoped that the Institute Transactions can be made an up-to-date record of metallurgical advance of all kinds. For the present, at least, the activities of the Committee include the refining and preparation of the non-metallic products such as phosphate rock, precious stones, cement, lime, gypsum, building stones, etc. Papers covering any of these subjects are desired. General papers covering geological, mining and metallurgical phases of an ore deposit can be sent either to this Committee or to one of the other Committees on Mining Geology or Mining Methods. C. W. GOODALE,Chairman. DARSIE C. BARD, Secretary.
