ToPoGRAPHtcAL MAcHIsE.-We witnessed on SAT-
urday morning las, opposite the Wal-street Ferry,
the experme tai u ial of machine invented by Messrs
Geo X. Clarke and Saml. Adams Of Antioch, Cahtor-
MIA for making Typographical surveys. Though APP
parenty imperftctly constructed, a. experimental
machines usually are, yet were surprised AMI

delueated the shape of the ground over which 1t was
drawn BY very simple eomboatl'n oil cones ana
friction wbte els. regulated by pendulum, motion Is
given to a roll of paper and grade-pen the relative
yeoctes Of which give exact profile OF the ground,
together with the ritz al and horizontal dsta ce uav-

over level surface the gradepen remains stationary,
while the paper moves at its maximum speed IL gong

speed that tn. grace pen moves IN vefuce one, ""
if the machine ia drawn perpendiculariy the paper
would stop while the pen, having increased to ITS max
mum speed would draw line in vertical direction
across it. number of practical and scenthc gentle-
men were present among whom we noticed Col RAM

names we did not learn. We understood thom all 10

the experiment The inventors pledge themselves 10
work with great facility, and with as much accuracy

inventors and scientific men generally.
IsPRoyID BLAST. PrPE-Mr VIM h. Cooper Of Dun
Kirk this State has introduced on the New York and
Erie Railroad form Of blast nozzle which has made
the few poor engines TO which II has been applied
equal to the best on the road for making steam IL has
been common to discharge the steam into the chimney
through round opening Mr.. C. simply forms It into
a ring or annular passage, that the escaping current
prese,ts great surface both ts exterior and lne-
nor sides to act on the smoke and drag it up the chm

for burning fluid, which compes the eItingulshiaent
of IL lights ~ the top unscrewed for hllmg ana also
holds the fluid in bag Of indiaTubber within tho
body Of the lamp, that if the latter DO broken tho
fluid cannot wei. be spilled upon the person by any pos

this arr ngement so that the consumption Of iud re-

railroad Disasters combined. This lamp will probably
prevent 80 per cent OF them and should be nInedeiy

one wheel 10 another il common 10 provide no teeth,
but smtly to let their smooth surfaces rub together.
A Mr. James Robertson has lately introduced IN Scot
land grooyed surface frictional gearing similar IN
the above except that the suraces let into each
other in grooves Messrs. Dron s. Lawson OF Glas-
