In lii^ paper in Nature, ProfesSor James Wilson of Dublin, gives the fol- lowing statements and results of an ex- examination of records as to color in Shorthorns, in illustration of the applica- tion of Mendel's law of inheritance: 1. Red crossed by red should give red calves. 2. White crossed by white should give white calves. .">. Red crossed by white should give roans. 4. Roans in-bred should give reds, white and roans in the proportion 1, 1. 2. 5. Roans crossed by reds should give roans and reds in equal proportions. G. Roans crossed by white should give roans and whites in equal proportion. This, giving heed to the expected ex- ceptions as indicated above, is what we find, viz: Four hundred and thirty-eight reds crossed by red give 413 red, 25 roan. Three whites crossed by whites give three whites. Seventy-one reds crossed by white give 3 red, 6S roan. Five hundred and fourteen roans crossed by roans give 152 red, 27S roan, 84 white. Four hundred and fifty-six roans crossed by reds give 226 red, 230 roan. Twenty-three roans crossed by whites give 14 roan, 9 white. For the breeder of Shorthorns this means that if he wishes to avoid white calves, he is limited to three crosses, viz: red with red, red with roan, and red with white. He gets whites when whites are bred together, when whites are bred with roans, or when roans are bred to- gether.âLondon Live Stock Journal. POULTRY NOTES. If there is such a thing as vermin about the poultry premises, it will find the lit- tle chick and nothing but heoric meas- ures will rid a premises of the pest. The farmer can make money on eggs if he can get the eggs. If he can produce eggs, and he ought to do this about as easy as to raise wheat or oats or barley. A writer in Poultry Success insists that white diarrhoea is hereditary. His plan of combatting it is to be careful
