John George Francis, Beach Rambles in Search of Seaside Pebbles and Crystals
“ If you hear the sea make a dull, booming noise during the night, be on the look-out two or three tides later, when the first shingle now thrown up has sifted and settled down. Large pebbles will then be found on the top of all, the process being much like that which takes place on shaking a basin of lump sugar.But it will be well for you to be always on the alert. The seaside elements must be coaxed and humoured, if you hope to get anything by their agency. A beach itself is exceedingly capricious. On some days you may walk for miles and remark nothing worth picking up ”
