CORWIN, IN SEARCH OF SLIDE MATERIAL 



73 



Welland Canal was visited at Welland and Allanburg, Ontario, Can- 

 ada (see figure 41). The nature of traffic and progress of improve- 

 ments in the route of this canal were noted carefully in anticipation 

 of the use of slides in the set on "The Great Lakes-St. Lawrence Water- 

 way." 



Thus, material was secured for slides on geographical, industrial 



Fig. 41. — Portion of the improved Welland Canal at Allanburg, Ontario, 

 Canada. (Land in the foreground is to be removed and canal straightened.) 



and historical subjects of not merely present but permanent interest; 

 slides that will be used not only in lectures at the Museum, but in 

 classes in every Milwaukee School that wishes to borrow them. Nor 

 is their use limited as above set forth, because when not reserved by 

 the City schools, they, as well as the other slides in the collection, are 

 available to any other school or organization in the City or State.
