without entering, so that there will be no danger of carrying 
particles of the excrement on the boots and spreading the infec¬ 
tion. 
j 3. Healthy birds must be placed on disinfected grounds. —If a 
piece of land is at hand to which the sick birds have not had ac¬ 
cess, and which is consequently free from the contagion, the 
healthy birds should be penned upon it; but if all of the land is 
infected, then a piece is to be selected and thoroughly disinfected 
with the solution mentioned further on in this paper. The fowls 
are to be restricted to this disinfected ground for several months, 
or even a year or more, if practicable. The drinking vessels and 
feeding troughs are to be new, or if used before, they must be 
soaked for twelve hours with the same solution before being 
placed in the new inclosure. 
4. Observations to be continued to note the first re-appearance 
of the disease. —Some of the fowls, though well at the time of 
removal to disinfected quarters, may be infected with the disease, 
and after the period of incubation, which varies from three to 
twenty days, will sicken. It is necessary, therefore, to make a 
careful inspection of the excrement each morning for at least three 
weeks after the separation of the sick fowls. If yellow urates are 
discovered, the birds must be watched until the sick one is de¬ 
tected. To facilitate the early discovery of such sick fowls and 
prevent infection of the healthy ones, it is advisable, where prac¬ 
ticable, to separate the birds into lots of two or three each at the 
start; and this separation may always be practiced as a last resort 
where the disease successfully defies our efforts for a considerable 
time; but where this is impossible a little patience will generally 
enable one to pick out the sick before any harm has resulted. As 
soon as the sick bird is removed the excrement must be scraped up 
and burned, and the run must be again sprinkled with the disin¬ 
fectant ; or, the well birds may be changed to fresh ground, as 
before. This method of management is to be continued as long 
as new cases of the disease occur. 
By a careful observance of these rules one can frequently 
check the disease with a loss of but one or two fowls out of a 
large flock.
