224 THE STRUGGLE FOR EXISTENCE v

 Socially, the " master " of four or five apprentices

 forty, or four hundred, or four thousand, " hands," 

 and the odds and ends of technical knowledge, 

 formerly picked up in a shop, .are not, and cannot 

 be, supplied in the factory. The instruction for-

Institutions of this kind on varying scales of
