remedies are given in the order of their popularity. 
YOLKS, COLOR INFLUENCED BY FEED.—Prof. 
Atwood showed that when wheat, oats, or white corn 
were fed alone or in combination, with beef scraps to 
balance the rations that the yolks of eggs were very light, 
entirely too light for the fancy trade, but when yellow 
corn was fed the yolks were very rich in color. It is 
thought that green feed, especially green grass or other 
green stuff, clover or alfalfameal, tend to make the yolks 
of eggs rich yellow in color. It would seem that any 
feed which makes butter yellow when fed to a cow would 
make the yolks of hens fed on the same kind of feed 
yellow. 
ZENOLEUM.—Zenoleum, creolin, naphthol are all 
4isinfectants and germicides, the base of which is the 
phenols, all having the phenol (carbolic acid) odor. They 
are recommended as disinfectants and germicides and a 
weak solution of them is used to disinfect incubators, 
their use seeming to improve the hatch and to be of some 
advantage in making the chicks healthier and more re- 
sistant of white diarrhoea.
