as lumberman. Iu his work Mr.. Garland has
been assisted by Messrs. Mcintyre and Kempt
Rust Mcintyre. These gentlemen
have had practical experience. have seen ex.
periments tried, and all successful methods OF
constructing boom they have adopted in The
| st. Paul boom. To express it truthfully. they
contend they have constructed model boom,
all the appointments, appurtenances and i'm.
rrovementS OF such work being used
in the present structure. The
late thaw somewhat retarded the
work, but new freeze came to their relief and
| the contractors will have their work completed
as required by contract, before April 10th
proximo. In fact the boom has so far pro-
gressed towards completion, that at this time
1t is in condition to receive and take care of
logs, were the river covered with them between
the boom and st. Anthony falls. A force of
lUO men are at work, and larger number were
employed just previous to the late thaw.
The piles used are twelve inches at the point,
thirty to thirty-two at the head or butt, and
are driven in place by two pile drivers of $500
weight. These are operated by engines, one
place upon sled or runners, and is
pulled from place ITO place over
the ice; the other is on foat or fat-boat and
Is mo'red in position to drive the pier-piles,
where the river current has prevented the for
nation OF ice. Teams, men, the noise of work,
the putt of the engines and tho systematic di-
reotlons of the superintendent make up the
busy and BUSTING sceue of industry.
TIRE IMPROVEMENTS.
Heretofore in the building of boom crib
work filled with stones has been tho mode used
in CO. structing the piers. These in the course
of time made current eddies, which formed
sand bars to their rear aud caused wash
around their base at the upper sde-eventu-
ally they'd topple over. Again, they pre-
sented bulk-head surface to the flow
of the water and the jam of the logs. This
again was and is a cause of insecurity, and
ultimately au overthrow of the piers. This is
obviated by the new style of pier used in the
st. Paul boom. Crib-work is discarded alto
sether; the piers are made of piles, and present
little or no surface to the water, and and in no
way obstruct the flow of the current to for m
hltering eddies. The weight of the jam of logs
acts directly downwards, and thus strengthens
the piers-the slant of the cap timbers being
up stream. In other words, it is the principl
adopted in the construction of all dams-a
slant or angle towards the water flow, instead
OF the old manner of presenting q full, fiat,
upright surface against which the water had
The constructors of the boom have
introduced the above method after
full and successful trial of its merits on the
Chippewa river. Here it has proved COM
plete success, and all new booms are built in
for piers. If SO successful in the Chippewa,
where the current is even swifter and stronger
than in the Mississippi river, there's no reason
why the new boom should not fulfill every and
all the expectations entertained for it by Messrs
Mcintyre, Rust and Kempt. The opinion has
been generally hazarded by sHch rs are opposed
to the success of the St. Paul boom, that it
could not be operated in the Mississippi river.
The current was too strong, etc, and the old
boom which fell into disuse is cited as a reason
for the opinion. To that the reply is made, that
it was . orib-work pier and presented
that very obstruction and obstacle to the action
of the water, which the piers of the new boom
avoid altogether. If any further assurance
need be given it is presented in the fact that
the boom contractors, who have built it, have
contracted to run it for five years. They have
confidence in it begotten by long years of ex-
perlence in connection with the Eau Claire
Lumber company, and on all the waterways
given up to logging in the States of Wisconsin
and Minnesota.
The above only gives what is to be arranged
and speedily finished to meet the requirements
of the first season" next summer. If the
business increases, as the Indications are that
1t WILL the system of sheer-booms and asscrt-
ment grounds will be stretched from tho falls
to the boom and from the boom to the railroad
bridge above this city; the company's charter
gives the right of domain over the waters of
the Mississippi between these mentioned
points.
In conclusion, the word may 20 forth as a
veritably the status of affairs, that the st. Paul
boom IS virtually an ACCOMPLISHED fact.
