Mr. Carr, the able and intelligent agent of Messieurs Swanzy, brought me sundry pieces and furnished me with the following notes. The 'belemnites' are picked up at the stream-mouths after freshets; but the people, like all others, call them 'lightning-stones' (_osraman-bo_) or _abonua_, simply axe. They suppose the _ceraunius_ to fall with the bolt, to sink deep in the earth, and to rise to the surface in process of time. The idea is easily explained. All are comparatively modern, and consequently thinly covered with earth's upper crust; this is easily washed away by heavy rains; and, as thunder and lightning accompany the downfalls, the stones are supposed to be the result. The _osraman-bo_ are used in medicine; they 'cool the heart;' and water in which they are steeped, when given to children, mitigates juvenile complaints. One of my collections owes its black colour to having been boiled in palm-oil by way of preserving its virtues; it resembles the _basanos_ of Lydian Tmolus; but the Gold Coast touchstone is mostly a dark jasper imported from Europe. The substance of the thunder-stone is the greenstone-trap everywhere abundant, and taking with age a creamy patina like the basalt of the Hauran. I heard, however, that at Abusi, beyond Anamabo (Bird-rock), and other places further east worked stones of a lightish slaty hue are common. About New Town and Assini these implements become very plentiful. Mr. S. Cheetham informs me that the thinner hatchets, somewhat finger-shaped, are copied in iron by the peoples of the Benin River. These expert smiths buy poor European metal and, like other West Africans, turn out a first-rate tool. Axim seems to have been a great centre of stone-manufacture. Mr. Carr showed us a dozen huge boulders of greenstone, chiefly at the eastern angle of the wart that bears, in dangerous proximity to his stores, his powder-magazine. The upper surfaces are scored and striped with leaf-shaped grooves, formed like old Greek swords; some of them are three feet long by three inches wide and three deep. I made a sketch of the place; Cameron photographed it, and on return carried off a huge slice of the block, which is now in the British Museum. We afterwards found these striated stones on the sea-ward face of St. Anthony Fort, in northern Axim, and on other parts of the seaboard.
