But we must do Mr. Douglass the justice to observe that his 
remarks on the breeding and rearing of Ostriches, and on the 
general management of an Ostrich farm, are not only original, 
but of much practical value. His long personal experience as 
one of the largest Ostrich farmers in South Africa, and the 
success which has attended his experiments in designing and

We fear, however, that with a good many people there is no 
other aim but that of making a collection of beautiful or rare 
natural objects, and that as soon as this is accomplished there 
is an end of Entomology. 
Of those who turn their collections to good account the 
percentage is probably very small. It is perhaps, therefore, 
quite as well that Mr. Farn should, in his preface, offer some 
remarks on this point. ‘ While giving practical details,” he 
says, ‘‘ of how to rear, capture, and preserve specimens, it must 
not be thought that the end to be attained by an entomologist is 
simply the acquisition of a collection. Apart from the pleasure 
of collecting—a pleasure it would be difficult adequately to 
describe—it should be borne in mind that this should be a means 
to an end; and perhaps the grandest end which may be striven
