morning, especially in rainy weather, on shrubs and grass ; 

 the smaller kinds under moss in the hollows of bones under 

 stones in the crannies of the bark of trees, or under the moss 

 at their roots by the sides of ditches, and in other moist 

 places. 



" Fresh-water Shells are to be sought after in quiet inlets, 

 on the sides of rivers, lakes, brooks, and canals ; in ditches 

 and ponds which are constantly full of water, and not disturbed 

 by cattle or other means, and on the weeds and other vege- 

 tables which grow in them. To collect them, a net or tin 

 spoon, pierced with holes, is required. The double shells, as 

 mussels, and such like, however, mostly live on, or under, the 

 mud. 



" The Marine Shells are very numerous, and, according to 

 their genera, inhabit various places. 



" The cavities and surfaces of the rocks on the sea-coast 

 afford periwinkles, limpets, sea-ears, mussels, &c. The two first 

 kinds must be severed from the place to which they adhere, by 

 swiftly passing a knife between them and the rock. If such 

 of the large stones as are moveable are overturned, many sorts 

 will be discovered sticking together on the underside ; and a 

 great variety may be found on the sea-weeds, especially after 

 a gale, when many of these plants are thrown up by the waves. 



" Such sand-banks and coral-reefs, as are for the most part 

 overflowed by the tide at its lowest ebb, abound with thorny, 

 and other oysters, &c. 



" Under the sand and mud, often to the depth of two or 

 three feet, live many various tribes of cockles, and other 

 double shells, many of which spout up the water, or sink the 

 surface of their beds by which they may be discovered ; and 

 here also, and in swamps, elephant's teeth, and other tubular 

 shells are to be met with, the animals only of which are above 

 the surface of the mud. 



" Several kinds live on the sea-shore, about low water mark,
