 1904-1914 — well supplied with interesting illustrated

 map of the continents with the Canal located, or a 

 sand model of the Canal itself. Some children w^ill

 maps or models of the Canal, with its two sea-level, 

 seven-mile entry ways and its middle section of fresh 

 water eighty-five feet higher, reached from the Atlantic

 Pacific side b}^ the two pairs at Miraflores which con-
