mots, murrelets, etc., and the birds of prey, there is no change in numbers 
that I have been able to detect. 
All the larger mammals are no doubt decreasing to a greater or less ex- 
tent. The beaver, martin and otter have become quite rare. The Indian 
market hunters are perhaps the most destructive to the ducks and game 
birds. Boy hunters destroy some small birds, but the professional bird- 
butcher and nest-robber have not as yet commenced their nefarious work. 
Of all cities that have come under our notice, Cheyenne surely 
deserves the first place as a bird refuge. Birds are now many 
times more numerous there than fifteen yearsago. Causes: tree- 
planting, bird protection and English sparrow extermination. 
Why should not every American city learn from Cheyenne? The 
extermination of the sparrow in a given locality is merely a ques- 
tion of a little prize money for distribution among the boys 
who will produce during a given season the greatest number of 
sparrows’ heads. 
Insufficient Data.—From six states the reports received were 
not sufficient in number to afford a satisfactory basis for a general 
average for each state asa whole. ‘These were Minnesota, Ari- 
zona, Tennessee, Kentucky, West Virginia and Maryland; but 
all the reports have been duly set forth. From four states— 
South Dakota, Delaware, Alabama and Nevada,—there are no 
returns, up to the date of going to press. 
SPECIES THAT ARE BECOMING ExTINCcT.—It is quite germane 
to our subject to state very briefly what species have been named 
it the reports before us as becoming extinct. In order to com- 
press this information into the smallest possible limit, we have 
gone through all of the 190 reports in hand, and made a com- 
plete list of the species named in answer to question No. 4— 
‘“ What important species of birds or quadrupeds are becoming 
extinct in your state?’’ ‘Te total number of localities in which 
each species is mentioned has also been reckoned up, and the 
figures are stated herewith. 
It must be remarked, by way of explanation, that many ob- 
servers used the terms ‘‘ becoming rare,’’ ‘‘ very scarce’’ or “‘ dis- 
appearing,’’ instead of ‘‘extinct,’’ or ‘‘ becoming extinct ;’’ and 
all species mentioned under such qualified terms as the three first 
quoted, have been excluded from our reckoning. Had they been 
included, the totals would be at least double the figures given. 
It is hardly necessary to remind the reader that many of the
