74 THE RABBIT 



of keeping fifty or even a hundred rabbits to the 

 acre for a series of years.' As Mr. Simpson, how- 

 ever, has demonstrated that it can be done, and 

 has answered Mr. Elwes's objections,^ it is evident 

 that no general rule can be laid down, and that 

 results must in every case depend upon the conditions 

 under which the warren is formed, and the nature of 

 the ground selected for the purpose. 



\A'hether warrens deteriorate in their productive 

 qualities in course of time, or not, is a disputed 

 question, to which Mr. Lloyd Price, however, has 

 given a decided answer. He asserts that if properly 

 managed, a warren does not deteriorate, but continues 

 its production per acre without cessation, subject only 

 to the chance of very inclement and wet seasons. 

 After fifteen years' experience, he found, in 1894, that 

 the same land which, under sheep, yielded 2s. 6d. per 

 acre, produced iS.f. per acre when under rabbits. 



All these subjects are discussed in his book 

 ' Rabbits for Profit, and Rabbits for Powder ; ' and are 

 dealt with also by Mr. Simpson and Major Morant in 

 their respective treatises above mentioned. 



The limited space at disposal here precludes our 

 discussing them at greater length. To these sources 

 of information, therefore, we may refer the reader
