be established in Grosvenor Square, or in some other of the 

 most wealthy districts. He would like to ask the deputation 

 where the money for four institutes was to come from. A 

 large technical and recreative institute such as that contem- 

 plated would cost _£loo,ooo. There must be a large and 

 costly apparatus, not only as regards teachers, but also for 

 materials and workshops ; in fact, technical education cost 

 about ten times as much as what might be called the common 

 literary education. He would strongly express a hope that 

 North London would establish an executive committee 

 similar to that in South London. It was far better to put 

 down one institution on solid and good foundations than to 

 attempt to put down two or three in an infirm and crippled 

 condition. With regard to the collection of the money, he 

 might tell them that the Polytechnic boys collected ,£3,000 

 between them.
