the summer seriously begins, without dong more than

very useful laws half way between the Reporting Com

The General Cont has now before il two important
measures, which, if its time could be saved from the
idle rivolty of those members who get up long discus
sons on petitions orders that Matched Jokes,
the beeteheaded and earnest stupidity of others that
bore the houses to egsae one side or the other of
the spirit Rappings, it might redeem its character.
One Of these is the additional supplementary Liquor
bill. ard the other the Hoosac Tunnel Loan bill. The
first would make more effectual law which has already
achieved much for the happiness of our people, and
which only needs to be universally enforced to reconcile
the highest conservatism with the largest spirit of
liberty The other would give Massachusetts the credit
OF being the first to eret the mountains, those only
barriers which stand to make enemies of kindred
tiOns on the same continent.

traction is undoubtedly ADEQUATE as will be plain TO any
who will carefully consider its nature
Let me explain little for the benefit of your readers
who not engineers Suppose that cylindrical pump
So inches in diameter with A. inch stroke, be con-
nected with pipe - inches in diameter and 80 feet
long. The capacities of the pipe and the cylinder will
be equal II the piston then be raised from the
bottom of the cylinder to the top the air in the
pipe will have to expand to double its space to fill
both the pipe and the cylinder and while the pressure

hours it would rarity to the extent the air in 300
miles of pipe AT that degree of exhaustion the exter
nal pressure the piston will be 1854 lbs than
the INTERNAL and there will be pressure of oneninth
that S4S lbs, available to propc load through the
pipe. AS the pipe is nearly level the resistance from
friction is nearly all that has To be by the pro-
pusion, and consequently mail Of 10000 halfOunce

then, the aerial equilibrium being restored resistance
would commence which would gradually destroy its

pOyed at once in exhaung the supposed 300 miles of
pipe it is plain that the work might be done in single

ing at different points, would undoubtedly be able in
hour to produce prOpeling force approaching much
nearer 10 whole atmosphere leaving, indeed only air
enough in the pipe to answer the important purpose of
attracting spring or cushion at the remote end to
prevent the mail from being shattered reduced to
homogeneous pulp by too sudden arrival
So far the mail itself is concerned it will probably
cost less tractye force to drag it bodily through pipe
of pretty smooth bore than drag with its proportion

of horse. power which would in given time drag it
hence TO New-YOrk, would in the time exhaust
pipe of sufficient bore enable atmospheric pressure TO
put it through in ten or fifteen minutes Multiplying
the horse power applied to the exhaustion will reduce
the time consumed IN the same proportion And in this
way may have hourly mails, or hafhourly with no
greater expense for carrying them than at present As
TO the and tear, that is another matter The fric
ton on the bags might be little more serious than at
present yet think this difficulty may be reduced to
rife. AS the load is constantly in contact with cold
pipe, the heat from the friction will be absorbed nearly
fast it is generated, and there is little danger that
the mail will take fire
The apparatus, small scale which Mr. Richard
shows at the Exchange, is very ingenously CON
sructed and works pretily. But of course no model
so diminutve can demonstrate the feasibility of the
operation, in large. Neither does an experiment of
