Ina paper On the anthracite coalfelds
of|Pemsylyania, Mr. P. ". Sheafer es-
timated the production Of that kind of
coal iii 1920, when anthracite mining was
begun, at SOS tons 1t is now 10000, 900
tons per annur. According to Mr..
! Sheafer, only one third Of the coal goes
into market !. the other two thirds IS vast
ed. being lost in lezmines and in prepare
ton The maximum product he estimat
ed at about So, 900, 900 tons per annum,
and, at the present rate Of. increase, this.
1 limit will be reached in the year 1900.
At that rate the anthracite eoal-helds
would be exhausted in 1876 years, say in
the year 2o65, Then we must have re-
course to- our bituminous Ecoal-helds,
whose area reaches the enormous extent
Of zoe, 900 square niles Of four hundred
times the area Of the anthracite. The
competition between the several anthrac-
ite coal companies, and between them
and the producers of bituminous coal, will
always keep the price moderate. Mr..
Sheafer doubted If Great Britain could
much increase its present enormous pro
duetsof I36 900, 900 tons, but at her pres
ent rate Of increase she will have exhaust
. ed her coal at about the time when our
anthracite resources are at an end.

The recent explorations Of the caves in
! the island of Borneo do not seem to have
accomplished particularly valuable results
The existence of caves containing fossil
{ bones has been proved, and at tie same
time the existence Of man, in the island
with the faana, whose remains are en-
tombedin these caves. But, both from
therecent nature Of this fauna, and from
the fact that the race of men whose re-
mains are associated with ii had already
reached an advanced stage Of civilization,
the discovery has in no way aided the
solution Of those problems for the unray-
Ielling 81 which il was originally promo
ted. No light has been thrown on the
origin Of the human race---the history o.
development Of the fauna characterizing
the Indo- Malavan sub-region has not beer
advanced nor. virtually, has any svi
dence been obtained toward showing
what races of men inhabited Borneo pre-
yiouslyIto the immigration Of the variou.
tribes of MaIavan stock which now people
the island. Furthermore, the presump
ton that the northwest portion Of Bornet
has too recently emerged above the wa
tiers Of the sea to render it probable tina
future discoveries will be made Of cav
deposits Of greatly higher antiquity thai
those already examined. had bee
strengthened.
