Bishop & Company. the transfer
agents In Honolulu of the EngeIs Cop
per Mining Company, recently receiV-
ed a report from Elmer 2. Paxton, the
manager OF the company, In which he
states that the output OF copper to:
the first four months Of the year
amounted to 1.673.931 lbs. as compared
with 1,277. 406 lbs. for the correspond
ing period OF the previous year. This
shows an increase Of 31.4% in the
present rate Of production. Paxton
also states that the average recovery
for the months Of March and April,
1911, shows an average Of 1885,, as
compared with an average recovery OF
1855 for the year 1916 and that this
marked improvement Is due to better
grinding by the substitution OF steel
balls for pebbles and to improved
methods In mill work. He also states
that the copper content Of the ore
milled Is 1850 compared with an
average Of 2.2S% for last year. This
he claims IL the result Of extracting a
larger proportion Of ore from the shaft
level and serves to show that the ore
Is Of better average quality in depth
than on the upper levels.
Ore Development
Continuing Paxton says:
"A large amount Of additional ora
has been developed On the fourth, fifth
and shaft levels OF the mine during the
past several months, following up dia-
mond drill work done last year. The
shaft level now extends beyond the
limits Of the upper levels and up to
date there has been no waste what
ever taken from that level"

100 feet Of the shaft. This tunnel
passed through 100 feet Of good mill

which win more than double our

ground and being Installed, and will
be IN operation within six weeks.
General Improvements
aAll Of the improvements outlined
n my last report are being pushed as
rapidly as possible. We are, however,
most eSasperating delays
on account Of war orders; car shortage
and consequent inability Of manufac:
turers TO make shipment on time. It
Is now impossible to secure delivery
