182 PROFITS IN POULTRY. 
good sense at the bottom of it, but a more active rorm 
of iron is desirable. The English poultrymen are much 
in favor of * Douglas’s Mixture.” This is made by put- 
ting eight ounces of sulphate of iron (also called cop- 
peras, or green vitriol) into a jug (never use a metallic 
vessel) with two gallons of water, and adding one ounce 
of sulphuric acid (oil of vitriol). ‘This is to be put 
into the drinking-water in the proportion of a tea-spoon- 
ful toa pint, and is found to be a most useful tonic 
whenever such is needed. So soon as the disease breaks 
out among the poultry, this should be given to the well 
to enable them to resist it, together with more nutri- 
tious and easily digestible food. 
One writer on the subject states that he made a satu- 
rated solution of alum, and whenever a bird was at- 
tacked, gave it two or three tea-spoonfuls, repeating the 
dose the next day. He mixed their feed, Indian meal, 
with alum-water for a week. Since adopting this he 
has Jost no fowls. Another writes that in each day’s 
feed of cooked Indian meal, for a dozen fowls, he added 
a table-spoonful of Cayenne pepper, gunpowder, and 
turpentine, feeding this every other day for a week. 
From what we have heard of chicken-cholera, it ap- 
pears to be a protest against improper feeding and 
housing rather than any well-defined disease. Fowls 
are often in poor condition on account of the vermin 
they are obliged to support, or they may be in impaired 
health from continuous feeding on corn alone. When 
in this weakened state, a sudden change in the weather 
may induce diarrhea, or a cold, which attacks the flock 
so generally that the disease appears to be epidemic. 
And being generally and rapidly fatal, it is called ‘‘ chol- 
era,” and the owner of such a flock at once writes us for 
a remedy for ‘‘chicken-cholera.”? A recent letter, from 
a friend in Massachusetts, is the type of many others 
received of late. This informed us that some of the
