GROWTH OF CALVES

HOW much will a Jersey calf 

 grow in length of leg, and in 

 depth of body as it passes from 

 calf-hood to maturity? To secure 

 definite information regarding the 

 growth of calves, I measured six Jersey 

 heifers when they were six months old 

 and again when they had matured into 

 four and a half year old cows. The six 

 heifers varied from two months to seven 

 months of age when I first measured 

 them, but averaged six months old. 

 The last measurement was taken when 

 they were four and one-half years old. 



I find that they average 32.8 inches 

 high as calves, and 47 . 9 inches high 

 as mature cows. They gained 15.1 

 inches in height. I find that 11.1 

 inches of the gain in height came from 

 a deepening of body or chest, and 4.0 

 inches from a lengthening of the legs. 

 From an inspection of the table it will 

 be observed that the calves grew in 

 length of front legs as much as two to 

 five and one-half inches, but it will be 

 observed that their growth in height 



came principally from deepening of the 

 body. 



Also I would call attention to the fact 

 that the heifers were wider through the 

 thurls at five months of age than 

 through the hips, but after they had 

 become mature cows they were wider 

 through (or across) their hips, than 

 across their thurls. 



After the calves had been measured 

 notes were made as to what kind of 

 mature cows they would grow into. 

 In checking over the notes after the 

 heifers had matured into four year old 

 cows, these prophecies were found 

 remarkably correct in most instances 

 regarding both the form of udder and 

 of body conformation. But in one in- 

 stance a nice heifer began to sway in 

 her back at eighteen months of age, 

 and became very swayed as a two-year 

 old. We find that the udder and teat 

 formation is fairly evident at five 

 months of age. 



The measurements of cows and 

 calves are as follows: — • 



An Old Problem Restated 



The Relation Between Religion 

 AND Science: a Biological Ap- 

 proach, by Angus Stewart Wood- 

 burne. The University of Chicago 

 Press, 1920, pp. 103. 

 Speaking more precisely, Mr. Wood- 



burne might have called his approach 



psychological rather than biological. 



He holds that science and religion have 



often been thought to be antagonistic, 



because the latter claimed a supernatu- 



ral origin; but that as a fact both of 

 these "attitudes" are purely human in 

 genesis, having their foundation alike 

 in the human instincts. Science he 

 considers to be an explanatory attitude, 

 while religion is an evaluatory attitude. 

 On this basis, he thinks there can be 

 no conflict of interests, but rather there 

 must be a co-operation of the two types 

 of attitude, to the end that human life 

 may be made fuller, richer, and more 

 satisfying. — P. P.
