2. _Fumigation_. Fumigation with sulphur is the only practicable method
for disinfecting the house. For this purpose, the rooms to be disinfected
must be vacated. Heavy clothing, blankets, bedding, and other articles
which cannot be treated with zinc solution, should be opened and exposed
during fumigation, as directed below. Close the rooms as tightly as
possible, place the sulphur in iron pans supported upon bricks placed in
washtubs containing a little water, set it on fire by hot coals or with
the aid of a spoonful of alcohol, and allow the room to remain closed for
twenty-four hours. For a room about ten feet square, at least two pounds
of sulphur should be used; for larger rooms, proportionally increased
quantities.[55]

3. _Premises_. Cellars, yards, stables, gutters, privies, cesspools,
water-closets, drains, sewers, etc., should be frequently and liberally
treated with copperas solution. The copperas solution is easily prepared
by hanging a basket containing about sixty pounds of copperas in a barrel
of water.[56]

4. _Body and bed clothing, etc_. It is best to burn all articles which
have been in contact with persons sick with contagious or infectious
diseases. Articles too valuable to be destroyed should be treated as
follows:

_(a)_ Cotton, linen, flannels, blankets, etc., should be treated with the
boiling-hot zinc solution; introduce piece by piece, secure thorough
wetting, and boil for at least half an hour.

_(b)_ Heavy woolen clothing, silks, furs, stuffed bed-covers, beds, and
other articles which cannot be treated with the zinc solution, should be
hung in the room during fumigation, their surfaces thoroughly exposed and
pockets turned inside out. Afterward they should be hung in the open air,
beaten, and shaken. Pillows, beds, stuffed mattresses, upholstered
furniture, etc., should be cut open, the contents spread out and
thoroughly fumigated. Carpets are best fumigated on the floor, but should
afterward be removed to the open air and thoroughly beaten.
