The figures in the table speak for themselves, and Prof. Forbes’ general 
conclusion as stated in his own language is: “I do not believe that the 
horticulturist can sell his small fruits anywhere in the ordinary markets 
of the world at so high a price as to the robin, provided that he uses 
proper diligence that the little huckster doesn’t over-reach him in the 
bargain. In other words, while the bird is far too valuable to exterminate, 
at least until we are sure we can replace him by some cheaper assistant, 
yet he is not so precious that we need hesitate to protect our fruits from 
outrageous injury. Indeed it seems likely that the ordinary destruction 
of robins by gardeners does not more than compensate for the destruction 
of birds of prey in the interests of the poultry yard—removing that excess 
of robins which, in the more natural order, would fall victims to the 
hawks and owls.” 
Thess conclusions are cautiousand certainly within the bounds of the 
experimental data upon which they are based. The results arrived at are 
founded upon a thorough and painstaking examination of one hundred 
and fourteen stomachs, and, coming from a man of such known standing 
as Professor Forbes, challenge our attention. 
In Vol. I of the Wisconsin Geological Survey, Mr. F. H. King devotes 
a small portion of a paper on the “Iconomic Relations of Wisconsin 
Birds” to a consideration of the robin. Thirty-seven stomachs were ex- 
amined. 
Animal food was found in 34 stomachs. 
Vegetal food was found in 13 stomachs. 
Adult forms, 16 were found in 24 stomachs, 
Pupe, 6 were found in 2 stomachs. 
Larvee, 49 were found in 19 stomachs. 
Insect eggs, 9 were found in 2 stomachs. 
Hymenoptera, 14 were found in 3 stomachs. 
Lepidoptera, 26 were found in 13 stomachs,
