Another Scientist in the Canadian Government Department of Fisheries, improvised an ingenious method for a non-swimmer to cross a stream that is deeper than the height of the non-swimmer. As with many brilliant solutions, it was simple. This ordinary looking genius discovered that by carrying a heavy rock under each arm while holding his breath, he could walk along the bottom of the stream or river to the other side. This method is not recommended for people with emphysema or other lung afflictions, nor is it recommended for very wide rivers and streams. Peter Clement Davis
