looked for Th7re Is n certainty in both light
and power and in the special directions in which
the leading Suirits are engaged there are al
ready fixed results aud the industrial world is
reaping the benefits.
An exchange SAYS II Is said that there are
already thirty electric light companies in End
land with capital OF over sS0OWlOOL The
number in France is less, but the capital repre-
sented Is nearly as great There are over utty
companies in America and the capital Is con
siderably over 100000. The rapid growth 81
this new application of a latent power Is some
thing marvellous 1t is also expected that out of
such II rush into new schemes there would be
some bogus affairs and some disaster. This Is
the case in all new enterprises which have such
sudden rise, and II Is well TO consider what the
outcome is 10 be.
Its reported that the Dominion Steamship
company are about to take several OF their
steamships off the Montreal route, owing TO
the lack of freight IN addition 10 their
regular weekly line, n number Of steamships
have during the past two or three years
been employed on This route; but now bust
ness Is SO poor that the company have 10 seek
employment for their vessels elsewhere. THE
wretched loading SYSTEM says n Montreal
dispatch to the Chicago Tribune, "has done
much to divert the American grain trade from
the ST. Lawrence route, and the commerce of
Montreal suffers in consequence. The immense
subsidies ppid annually to the AllOns
serve to recoup them for their loss of business"
Among the results of the years work AT the
Johns Hopkins University the Investigations
which have been carried on at the Chesapeake
Geological laboratory under DR.. W. X. Brooks
have been of especial scientific interest MS well
as of great economic importance. Dr. Brooks
pointed out four years ago that as the growth of
an animal is limited by the supply OF the least
abundant of the necessary ingredients of its
food, the supply of oysters was in all probability
determined by the amount of carbonate of lime
available for shell. formation DR., Brooks now
finds that bv placing the oyster eggs in u vessel
OF water with good supply of such shells as
decOmpose readily, he can hasten the formation
of the shell, and carry the young far
thcr In thrIy-Sx hours than they
have ever before been carried in eight
days At the same time the young are much
more healthy and vigorous than those reared
without supply of lime. This discovery of Il
way 10 reduce the most critical period in the
life of the oyster from eight days to thirty six
hours is of great value After the shell Is
formed the young oyster can be kept alive for
several days but is gradually starved to death
The only point which now remains in practical
oyster propagation from the egg is the method
OF supplying the young with food. This. Dr.
Brooks thinks, requires nothing more than n
little patience. The spawning season Is now
over, and II is not probable that any further adj
vnnces will be made In this direction this year.
method of feeding the young oyster will prob
ably be found out next season by DR.. Brooks or
by Lieutenant Winslow, U. s. NJ an officer Of
