l8 BY THE DEEP SEA. 



will require a small net, or rather two nets, for one that is 

 suitable for catching the small and delicate forms one finds in 

 the rock pools or swimming near the surface of a smooth sea, 

 will not be strong enough for drawing through the rough weeds. 

 The one should be of fine muslin to retain minute forms ; the 

 other should be really a "net," of the very smallest mesh 

 possible. 



On the rocky shore you will find the greatest abundance and 

 variety of the marine algae or seaweeds, most of the crusta- 

 ceans, nearly all the anemones of the littoral zone, a number 

 of species of fishes, many of the tube worms, the sponges, the 

 tunicates, and such moiluscan forms as the periwinkle family, 

 the limpets, dog-whelk, tops, slit limpet, smooth limpet, cowry, 

 and sea-lemon. On the sandy beaches you will find only such 

 seaweeds as have been washed in by the waves, shrimps, the 

 masked crab and the angled crab, launce or sand eel, the 

 razor-shell, cockle, tellen-shells, horn-shells, the natica, and 

 other shells. 



On the shingle beach little will be found besides empty 

 shells and heaps of more or less damaged seaweeds, which, 

 however, are well worth examining, for occasionally one may 

 find uncommon kinds there, and among them specimens of 

 animal life. But it is to the rocky-shore we advise our readers 

 to give most attention. The rocks, their pools and crannies, 

 will engross the attention more, and the harvest will be greater. 

 By a little local study it will be found that certain winds will 

 cause the heaping up of certain shells on one particular part of 

 a beach, whilst other winds bring other things to the same or 

 different parts. This knowledge acquired, you will put it to 

 practical use by finding out what was the direction of that stiff 

 gale that blew last night, and then bending your steps in a 

 particular direction, you will be able to take your pick of the 

 shells before the hinges have become broken and the valves 

 separated. There are many species of mollusca whose shells 

 you will only acquire in this way, unless you are able to go
