THE COAL TRADE BULLETIN. 49
BELGIUM COAL PRODUCTION.
The preliminary figures on coal production ia
Belgium for last year show a slight decrease in
production, as compared with the previous year.
The output by districts was as follows, in metric
tons:
1903. 1904. Changes.
Borinage 4,705,110 4,599,640 D.10o,4.0
Center 3,741,250 3,655,810 D. 85,440
Charleroi S,276,000 8,092,800 D.181,200
Namur 774,000 729,020 D. 44,980
Liege 6,416,880 6,302,755 U.li4,125
Total 23,913.240 23,380,025 D.533,215
A decrease was shown in every district. At the
close of 1903, nearly all the collieries had large
surplus stocks on hand, and most of them cur­
tailed the output to some extent, until these stocks
were, at least partially, worked off. The consumption
in 1904 was equal to that of the pre­
vious year, and work has been active since the
opening of the current year, except during the
miners' strike, which covered parts of February
and March.
Wonderful Scenic Trip Across Rocky Mountains
to Oregon Exposition.
In certain respects the excursions to the Lewis
and Clark Centennial Exposition, Portland, Ore
gon, via Pennsylvania Lines, beginning May 23d
and continuing through the summer, offer advantages
never before presented to exposition
visitors. The trip to the Oregon exposition, in
addition 'to the attractiveness of the extensive
exhibits, includes the journey through the scenic
wonderland of the Rocky Mountains and the
Cascade Range, and what American has not looked
forward from the days of the geography class in
school to the time when those great sights should
he seen in reality? The time was never so favorable
as now. The trip may be made less expensively
than ever. For only a slight difference
in fare tourists may extend their trip to San
Francisco and Los Angeles. The return trip may
be made over a different route, enabling travelers
to view much more of the West. For full particulars,
fares, dates of special excursions to Portland
on account of conventions, through time and pas­
senger service apply to J. K. Dillon, District Passenger
Agent, 515 Park building, Pittsnurgh, Pa.
The Youngstown & Southern railroad, which
passes through the heart of the North Lima coal
fields of Ohio will derive its principal source of
revenue from the transportation of coal. The com­
pany is capitalized at $1,800,000, half of the stock
having been taken by Youngstown capitalists.
