That was a curious sensation which
the citizens of Perry, Oregon, must have
felt, when they discovered that their
town had been overlooked in the taking
of the census. A way is to be found of
Fighting the matter, though the fifteen
days assigned for taking the census
have passed. Here and there in cites
where the official enumeration went for
ward with all due hustle, individuals are
now turning up with the convlc-
ton that they have not been listed.
Whether oversight in the cases of ind
viduals will be remedied remains to be
seen.
Doctor William IL Park of New York
| assured the delegates to the National
Association for the Prevention of Tuber-
cuIosis that. only 212 per cent. of. the
cases in that city come from infected
milk, butter or meat from bovine sources
This small percentage, he declared, is
found mainly in children, and as a 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

A book on "The Corrosion of Iron
and Steel" by Alfred Sang, discusses
question that is of vital interest to archl-
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 eff service,
remarking that data thus far collected
seems to indicate that the vibration of
the rails in service tends to protect
them This leads to Railway Age TO
suggest that perhaps corroslon is due to
weak currents of electricity. 1t refers
to the fact that if a permanent steel
magnet is struck with a hammer and
caused to vibrate it will be injured mag
netically by the treatment, and If the
hammering is continued it will be entire
ly demagnetized in time. From this
fact, remarks the Railway Age, is 1t
not reasonable to assume that the Vibra-
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 cOrrOSlOn, and that with
the cause thus removed cOrrosiOn Will
not occur? The question is a very in
teresting one in this age OF steel, with
the metal being utilized IN every con-
ceiVable way.
Troubles experienced by the Panama
canal excayatOrS Ill the difficult section
known as the Culebra cut are convert
ing many of those who have been advo-
eating a sea-evel canal to the view that
the government was wise in adopting
the lock plan. 1t appears that the pres
sure of the earth on both sides of the
cut at Culebra causes the ground to
hump up in the ditch which is to be
the canal bed. This of course necessi-
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
ried down to sea level the excavation
would be tremendous, and the side pres
sure might entail an endless task IN this
regard. at tremendous expense.
