considered more in detail at another point.) After about 145 pounds 
of CS, had been exposed, occupying from fifteen to twenty minutes, 
the fumes had become so dense that we were forced to withdraw. 
The building was then carefully locked and left for twenty-two hours. 
People passing on the street at the time the exposure was being made 
and those having business in adjoining rooms complained of the exceed- 
ingly disagreeable odor, but at a visit to the premises later in the day 
the writer could detect but very slight traces of the odor on the street, 
even close to the door. No guard remained near the building during 
the day. 
On Monday morning, at 4.45, the store was opened for ventilation. 
The density of the fumes had greatly diminished, but a watch was 
kept to see that no one passed close to the door with a lighted cigar 
until the fumes had mostly disappeared. In forty-five minutes the 
store was so well aired that but little of the disagreeable odor 
remained, though for several days slight traces of the odor lingered 
in the room. 
An examination of many boxes of the infested stock on the lower 
floor disclosed many dead beetles, but no living ones. Unopened boxes 
of stock in the gallery were examined, and these showed only about 
one live beetle to every one hundred dead ones. So far as could be 
determined at the time, the treatment was very successful, and the 
proprietor expressed himself as very well pleased with the result. 
The suggestion was made that future trouble with the cigarette 
beetle might probably be avoided by treating incoming stock with CS, 
in a quarantine chamber before placing it in the sales room. In the 
basement the writer was shown a large, zinc-lined, air-tight box, hay- 
ing 18 cubic feet capacity, which has been used as a moistening cham- 
ber. Upon being assured that this was an admirable thing for a 
quarantine box, the proprietor declared it his purpose to adopt the 
suggestion and treat all new or suspected old stock in this way. 
DANGERS IN USE OF CARBON BISULPHIDE. 
It is customary when anything is written concerning the use of this 
very volatile and highly inflammable liquid to emphasize the danger 
from fire in the presence of the fumes, and it is usually pointed out 
particularly that even alighted cigar may cause a disastrous explosion. 
The writer has also seen printed mention of the danger of. liberating 
the fumes in the presence of heated steam pipes. So it seems that a 
brief mention of a few other points of danger may not be out of place 
here. 
No electric fan should be allowed to run in the presence of the fumes, 
as it is liable to Ne off occasional sparks. For the same reason there 
would be danger in turning on an incandescent light, and though the 
danger in turning ‘Sit suc i a light is less than in turning it on, there 
is still too much chance of forming some connection which would pro-
