These various dis- eases must be borne in mind in determining the nature of any outbreak. Treatment.— The treatment may be divided into three parts : 1st, measures for preventing the introduction of the contagion; 2d, measures for suppressing the dis- ease in the flock, and 3d, treatment of individual birds. The prevention of diphtheria is mucti more successful than its cure, and, besides, it saves much time and many valuable birds that will succumb before treatment can be com- menced or notwithstanding treatment. Fowls should not be allowed to mingle with those on neighboring premises. If some of the birds have been to a show or if new birds have been purchased for the flock, quarantine them at a distance from the home flock for thirty days before they are allowed to go together. While in quarantine the}- should be examined from.
