Doctor William II. Park of New York
assured the delegates to the National
Association for the Prevention of Taber-
culoSIs that only 212 per cent. of the

Inns small percentage, he declared, IS
found mainly In children, and as broad
generalization it is safe TO say that
adults contract tuberculosis from human
beings and not from impure milk or
food. People who have had their doubts
about the slaughter Of herds in the in

Will continue to have them after reading
this opinion.
A book on 1.-THE Corrosion of Iron
and Steel" by Alfred Sang, discusses
question that is of vital interest to arehi-
tects and erecting engineers in the build
Ing trade. In it the author mentions
the various theories as to the cause OF
corrosion in iron and steel and calls at
tention to the curious fact that steel
rails In service rust far more slowly
than those which are out ef service,
remarking that data thus far collected
seems to Indicate that the vibration of
the rails III service tends to protect
them. This leads to Railway Age TO
suggest that perhaps corrosion is due to
weak currents of electricity. 1t refers
to the fact that If permanent steel
magnet is struck with a hammer and
caused to vibrate it will be injured mag
netlcally by the treatment, and If the
hammering is continued it will be entire
~ demagnetized in time. From this
fact, remarks the Railway Age, is it
not reasonable to assume that the yibra
ton of the rails incident to traffic tends
to prevent the formation of the electric
currents which are supposed to be the
cause of the corrosion, and that with
the cause thus removed corrOsion will
not occur? The question is very in
teresting one in this age of steel, with
the metal being utilized ia every con-
ceivable way.
Troubles experienced by the Panama

the government was wise III adopting
the lock plan. 1t appears that the pres

cut at Culebra causes the ground to

tates extra excavation, but it is crafty
ing to know that the engineers feel no
alarm as to the ultimate result of their
operations. If the ditch had to be car

would be tremendous, and the side pres
