 tion of keeping proper milk records. 



The Montgomery- Ayrshire cross-bred herd now stands 

 at 73 head. 



The heifers and cows in the herd are put to cross-bred 

 bulls of which there are three with the herd : 



(1) Black Diamond No. 3, by Mossgeil Titanic, out of 



Rengni No. 149. 



(2) Goliath No. 8, by Lessnessock Wildfire, out of 



Diwali No. 77. 



(3) Mammon No. 9, by Lessnessock Wildfire, out of 



Timki No. 80. ' 



The Mossgeil half-bred bull is used on Lessnessock 

 heifers and the Lessnessock half-bred bulls on Mossgeil 

 and Carston heifers. A Carston half-bred bull will be 

 added to the herd in place of one of the Lessnessock bulls 

 as soon as possible. 



We have now calves from the following crosses, and 

 careful observations and records will be and are being kept 

 with a view to collecting data as to hardiness, milk yield, 

 etc. 



Half-bred .... Ayrshire bull x Montgomery cow. 



Three-quarter-bred . . . Ayrshire bull x Ayrshire-Montgo- 



mery cow. 



Double cross-bred . . . Ayrshire-Montgomery bull x 



Ayrshire-Montgomery cow. 



Quarter-bred . . . . Ayrshire-Montgomery bull x 



Montgomery cow. 



Plate II shows two typical double crosses at five 

 months, and Plate III, fig. 1 a three-quarter-bred at five 

 months. 



At present it appears that three-quarter-breds usually 

 have a longer, thicker coat, and are apt to be rather slower 

 doers at first than half-breds. They, however, do quite 

 well in the later stages. It is practically impossible now 

 to distinguish between half-breds and quarter-breds and, 

 as far as the experiments have gone, it appears evident that
