the same land, and also by the exacting nature of the work of 

 caring for them under such conditions. In manufacturing and 

 commercial operations there are no such limitations. The pos- 

 sibilities of development depend upon the extent of the demand 

 for the articles that are manufactured or sold, and only a small 

 proportion of the employees need to be persons versed in avi- 

 culture. But in competition with other manufacturers or mer- 

 chants those who understand domestic birds and know all the 

 different phases of interest in them have a very great advantage 

 over those who do not. 



Legislation and litigation. The rise of new industries creates 

 new problems for legislators, executive departments, courts, and 

 lawyers. An industry in which many people are interested 

 eventually reaches a stage where it is profitable for lawyers to 

 specialize to some extent in laws affecting it, and politic for legis- 

 lators and administrators to do what is in their power to protect 

 the interests of those engaged in it, and to advance those interests 

 for the benefit of the whole community. A special field is open- 

 ing for lawyers familiar with aviculture and with its relations to 

 other matters, just as within a few years the field has opened 

 to teachers and investigators. 



The possible uses of a knowledge of aviculture to young 

 people who are naturally inclined toward intellectual professions, 

 art, invention, manufacturing, or trading have not been given 

 for the sake of urging students to direct their course especially 

 toward work connected with aviculture. The object is only to 

 show those who take an interest in the subject that it is worth 

 while to cultivate that interest for other reasons, as well as for the 

 profit or the pleasure that may be immediately derived from it.
