"A "a tuO AACxCAdu
shipping statistics of New Brunswick
shows that there are now registered il
that province 945 vessels, with an ag.
gregate tonnage of $50, 953-a great
falling off from previous years. More
than two-thirds of the tonnage is in
square-rigged sailing vessels, and over
fve-sixths of the total is owned in st
John.
"A scientific commission is searching
over Brazil for the healthiest part of
that country. In accordance with the
new constitution of the republic the
capital must be removed from Rio
Janerio, and the government has APP
pointed body of scientific gentlemen
to select the healthiest geographical
site.
"A splendid specimen of the back
sunfish, which is said to be very rare in
English waters, has just been captured
on the Lincolnshire coast, between
Gibraltar Point and Skegness. 1t meas
and five feet six inches in depth and
weighed close upon three quarters of a
ton. The fish has been sent to London
for preservation.
London scientists have recently
demonstrated that the purest air in the
cities is found about twenty-tive feet
above the street surface Heretofore it
has been thought that the highest floors
in tenement houses had the best air.
The Investigations above referred show
that the healthiest apartments are those
of the third floor
Colorado is coming to rank high as
a coal-producing state, ana it is proba-
BILE that her coal resources will eventu-
ally prove more Important and valu-
able factor in the progress and pros
perity of the state than her famous sill
yer wealth. The coal output last year
was 3, TO, 900 tons, worth over SIS, O00,-
600, and the number of miners en-
ployed in the coal mines throughout
the state exceeds 5000.
shipments of butter from Victoria,
during the season just ended. amounted
to about 5000 tons, and bonus of two
cents per pound was paid on all that
sold in London for between twenty and
twenty-five cents, while bonus of
three cents was paid to all that real
lied twenty-five cents and upward. It
was estimated that the government
would have to pay 5000, 900 in bounties,
but the public feeling is against this
sort of subsidy, because one leading
butter company has just paid dividends
at the rate of 20 per cent per annum.

There were confident anticipations
by the Department of Agriculture, of
Manitoba, of rs, 192, 900 bushels of wheat
from GIG, 664 acres, II, 763, 600 bushels of
oats from sos, ga acres, and 3,19S, 900
bushels of barley from s9,s2s acres for
the crop of 1892. These estimates were
realized from barley and oats; but fields
plowed for wheat in the spring were
injured by frost, and the exposure of a
large portion of the crop in open stocks
and badly constructed stacks reduced
the aggregate of wheat available from
Manitoba and the northwestern terri
tories to 5000, 600 bushels; nor has the
return to the producer exceeded go
cents per bushel.
The first firing was done on the
new proving grounds of the Bethlehem
iron works on the 2sth of July last.
Screens were arranged in connection
with electrical instruments for measur-
ing the velocity with which the shots
travelled. In the test made the object
was to obtain the velocity of $50
pound shot fred from an eightrinch gun
with charge of 81 pounds of hexago-
nal prismatic powder The standard
set down for these conditions is ZOO
feet per second, or at the rate of about
1900 miles per hour. The instruments
showed a velocity Of 1,7o3 feet for the
first shot fired; this came so close to the
standard that other tests were consid-
cred unnecessary. This is said to be
one of the most satisfactory tests made
in the history of modern ordnance.
