different localities; ono n Saxony, eight miles long,
through very hard gneins rock the other the
Mount Gents tunnel, through tho Alps also about eight
miles opg-about coubs length Of tho Hooslck tune
In those tunnels an actual progress has been made about
i've times az RAPID az that By hand labor The machinery
used consists OF small drills worked by compressed air
In tho Hoosick tunnel similar machinery viii be employed
but the plans Tor conducting operations are believed % be
superior 70 those used IN Europe Toe drills consist Of
small cylinders, four inches in diameter and nine
inches long, having hollow ps'ons through viii ii
the drill rod passes. Contrivances are added for
turning and feeding the drills The mum Der of strokes
per minute will be from two to three hundred The spaco
occupied by each drill will not exceed eight inches square
The supports consist of movable columns, upon which
from four 70 six drills can be placed. About twenty OF
these drills will be used ia the hea ing and experience
has shown that tho progress is twsye times rapid
BY hand, the rate in drilling. as compared with hand
labor, will be sixty to ono. The columns, with the at
tached drills, can be set up and removed with great
facility The holes will be blasted by means OF gun
powder and will be loaded by means Of aud ex-
peditous process and ignted simultaneously by cleo
tic battery The smoke produced by the bias, can DO
removed in lees than two minutes after the explosion by
means Of flexible hose, In which vacuum Is created
by exhaust fan placed on the outside OF the tunnel
The Great advantages claimed by the proposed plan OF
operations any others previously employed thess
J. Greater simplicity and economy In space In the drills
themselves 2 The facility with which the drills can be
der smoke DO removed. l. The ability to set up the
drills and put them In operation, without waiting until the
material blown down by the former blast shall have been
removed This Is peculiarly in the arrangement not
possessed by any other plan before proposed The
contr actors estimate that il progress Of ten feet por
can be made by the plans used In Europe at least twenty
feet day be made by the plans proposed the
Hoosicka rate Of progress which will complete the tun
nel In little more than two years.
