SOME NEW IDEAS 



water such as are found on Cape Cod. At these ponds, probably a boat 

 would not be needed. The pump could be set up on shore, and the diver 

 would descend the steep banks step by step. The water in most of these

 naturally occur to any amateur who uses them. The field is a large one. 

 There is plenty of room for pioneers. The reward for working in it will 

 be bountiful.
