| After scratching our way over a metre downwards through the shingle, we finally hit the waterworn rocks of the early Carboniferous. |
| The bones are black, brown or white, highly fragmented and waterworn to a variable degree. |
| This ware is characterized by a dull, reddish-pink body, usually dark-gray at the core, and by a gross waterworn gravel temper. |
| The houses are generally built of waterworn stones, without cement, but plastered with mud outside and inside. |
| Seaside and river gravel, which is composed usually of rounded, waterworn pebbles, is unfit for surfacing roads. |
| Sportrock sites are limited to accesible areas of high quality quartzite, and waterworn limestone. |
