drop on the tenth, after which the gain was again 

 favorable. It will be observed that four litters are 

 shown on he Weight Chart illustration. Litters No. 1 

 and No. 2 were of seven each, while No. 3 and No. 4 

 were of five only which served to explain the relative 

 average early growth of large and small _ litters. 

 Furthermore, Litter No. 4 was off-icolor, proving that 

 the parents were illmated for color production, and as 

 the weight also was not remarkable, the whole littef 

 went to the pot at eight weeks. Further than ex- 

 plaining the relative growths of many litters at a 

 glance, the whole may be compared to the standard 

 weight for the varietv of stock under observation bv 

 platting the standard weight on the chart and fixing 

 same with an ink line. One of the results of the in- 

 troduction of the graphic chart will doubtless be the 

 better formulation of our weight standards with re- 

 spect to relative ages. 



In explanation of the cost figures given in column 

 six of the Litter Record, reference is made to feeding 

 cost data shown on page 204. The daily feeding cost, 

 with the schedule specified, of a mature rabbit is 

 $0.0092, which fixes the weekly cost at $0,064. The 

 writer has determined that a litter of six youngsters at 

 six weeks of age apart from the doe will require very 

 nearly two normal feeds ; also that at 18 weeks old the 

 growing youngsters will require normal, mature feed. 

 Therefore, at six weeks' age the feed cost is one-third 

 normal, or $0,021, while at 18 weeks it is normal, or 

 $0,064. Now by platting these values on the Weight 

 Chart at the ages of six and eighteen weeks, striking a 

 line between them and assuming the vertical gradua- 

 tions to represent cents instead of pounds, we obtain 

 a graphic method of determining weekly feed cost at 

 any period. For example, note that the feed cost from 

 six to seven weeks is $0,023, from seven to eight weeks 

 is $0,026 (very nearly), from fourteen to fifteen weeks 

 is $0,052, etc. Of course, it is evident that these val-
