METHODS FOR COLLECTING AND PRESERVING ALG. 
Many excellent specimens of alge may be gathered from the beach, where they are 
thrown by the tides and waves, but satisfactory collections can be obtained only from 
the places where they are growing. Except in deep water, where the tide makes no 
appreciable difference, all collections should, of course, be made at low tide. The alge 
are procured in three ways: Those growing between tide lines or near the surface are 
collected by hand; at a greater depth they may be gathered by long hooks, rakes, or 
tongs; while those growing at great depths are obtained by dredging. These three 
methods differ greatly in their relative values. Those stations which may be reached
