his dam and her ancestors. . . . We have used white on white and 

 often had roan calves and in one instance had a red calf, but about 75 



We have had considerable experience in crossing the Shorthorn on 

 Angus. This we consider the best cross and the offspring is generally 

 better than either of the parents. When crossing red and black the 

 offspring are generally 75 per cent, blacks and even the second cross 

 will not bring 50 per cent, reds: when crossing roan and black, about 

 50 per cent, will be blue-roans, 10 per cent, red-roans, 10 per cent, 

 reds and 30 per cent, blacks. The Galloway color is much stronger 

 than the Angus, consequently more dark calves will be expected. The 

 Hereford cross is very strong as far as the white face is concerned and 

 about 95 per cent, of white heads can be expected but the red of the 



on Hereford cows. ? 



The black of the llnlstein seems to he particularly strong and when 

 crossed with red the offspring will be nearly black and will remain 



itself but very little. ... On the other hand, Holsteins take the roan 

 color very readily and when crossed on white !>5 per cent., and when 

 crossed on roan 75 per cent, of the calves will be blue-roan. It is our 

 experience that either the Holstein or the Hereford will take the roan 



The observed facts fit the following hypothesis so 

 closely that it is presented as a further working basis in 

 solving the problem of the prediction of the color and 

 color pattern in Shorthorn cattle.
