PHOTOGRAPHS 



The calves were photographed each thirty days during the first 

 six months which is the total period included in this experiment. 

 The illustration, Fig. i, portrays the equipment used in securing 

 these pictures. The background was divided into six-inch squares 

 and in order to secure contrast in the photographs of calves of dif- 

 ferent breeds, a black or a white background was used, according to 

 the color of the calf. The camera was placed upon a stationary 

 support and was situated at a uniform height and distance from the 

 background for each exposure.

No special attention was given the calves previous to being 

 photographed; therefore, the illustrations as shown, represent the 

 calves as they actually appeared upon the days the pictures were 

 secured. 



The chief value of a series of photographs, as herein presented, 

 lies in the fact that such illustrations furnish the experienced feeder 

 a better index in regard to the condition of the calf than it is possible 

 to give with tabulated figures alone. While a given ration may pro- 

 duce a fair individual when viewed at six months of age, the actual 

 merits of any calf feed should be apparent as effectively at one 

 period of the calf's development as at another.
