The oil wells of Italy comprise about 5, with a capacity of about 30
barrels per day, of a thick substance of 14 gravity. They are pumped
by hand, which, though primitive, is cheaper than steam, for both men
and women are employed, the former receiving as compensation for a
day's work 1 lira, equal to 20 cents; and the women 60 centessimi,
equal to 12 cents of our money. The wells are located in a deep
valley, and the oil carried up on the backs of donkeys to a refinery,
where it is treated, and yields from 2 to 5 per cent. of burning oil.
PERU.
It is proposed to build a pipe line from the refinery on the estates
of Henry Meiggs to the shipping port, a distance of about 7 miles. It
is stated that oil can be produced at this point for less than 1 cent
a gallon, and as the fields have produced from time immemorial, there
is no prospect of their early exhaustion.
ONTARIO.
The oil refinery at St. Thomas, Ont., is running day and night; 494
barrels of crude petroleum were brought from Petrolia for it in one
week recently.--_Stowell's Petroleum Reporter_.

RAILWAY NOTES.
The new track laid in this country during the year ending September
10, 1878, was 1,160 miles. During the six preceding years the number
of miles of track laid was: In 1872, 4,498; 1873, 2,455; 1874, 1,066;
1875, 702; 1876, 1,467; 1877, 1,176.
The statement made in the recent Narrow Gauge Convention, that
standard gauge freight cars weigh ten tons and carry ten tons, is
indignantly disputed by users of the latter. One gentleman, having
much to do with freight cars, says that the modern freight cars weigh
from 17,000 to 18,000 lbs., commonly carry (and that on long hauls)
28,000 lbs., are guaranteed to carry 30,000 lbs., while he has seen
them show on the scales 30,000 and 32,000 lbs. of load, and in one
case 35,000 lbs. The general tendency for some years has been to
increase loads without increasing, but in many cases decreasing,
weights of cars; and it seems quite likely that 30,000 lbs. will soon
be the standard load. The tank cars used for carrying petroleum have
an average capacity--and they are almost always run full--of 30,000
lbs. The Standard Oil Company, which has some 3,000 of such cars,
carried on four-wheeled trucks with the Master Car Builders' standard
axle, has run them with such loads for years, and only recently had
its first case of a broken axle, manifestly due to a defect in the
iron.
