THE ENGLISH SPARROW IN AMERICA. 



The following table shows how costly such an undertaking would be, 

 even were it certain that the lowest rate, one cent apiece for the first 

 year, would secure the desired result. It is more than probable, how- 

 ever, that at least three cents apiece would be necessary to accomplish 

 the first year's work, and alter this had been doubled for the second 

 year, it would be found inexpedient to continue so expensive an exper- 

 iment. 



Hypothetical table, showing the amount of money necessary to expend in bounties on English 

 Sparrows in Ohio for five years, at the rates of 1, 2, 3, 4, and 5 cents a Sjiarrow the first 

 year, the rates being doubled each successive year.

When it is remembered that all the assumptions and estimates upon 

 which these conclusions are based have been moderate in the extreme, 

 and that all the conditions are supposed to have been favorable for the 

 successful operation of the law, it will be seen how futile would be the 

 attempt to exterminate the Sparrow in Ohio by the offer of bounties. 



Some of the considerations which have not been brought into the cal- 

 culation at all, but which of necessity must affect the question mate- 

 rially, are the following : 



(1) The expense necessary, even at the moderate estimates submitted, 

 would be greater than any State could afford.
