FLINT IMPLEMENTS. 249 



so brittle, that implements made of it must have been easily 

 broken, and, in that case, the fragments would be thrown 

 away as useless, especially in a chalk district, where the 

 supply of flint would, of course, be practically inexhaustible. 

 Many implements, no doubt, would be left unfinished, having 

 been rendered useless, either by some misdirected blow, or 

 some flaw in the flint. Moreover, we should naturally expect 

 that in a bone-breccia of this nature, the flint-implements 

 would be relatively more abundant than in a Kjokkenmod- 

 ding. Each oyster furnishes but a single mouthful, so that 

 the edible portions evidently form a greater proportion of the 

 whole, in the mammalia than in the mollusca. The Kjok- 

 kenmoddings, therefore, would grow, cceteris paribus, more 

 rapidly than the bone-breccia, and supposing the flint-im- 

 plements to be equally numerous in both cases, they would, 

 of course, be more sparingly distributed in the former, than 

 in the latter. 



The objects of stone found in. the bone caves which we are 

 now considering, are flakes, both simple and worked, scrapers, 

 cores, awls, lance-heads, cutters, hammers, and mortar- stones. 



The simple and worked flakes are, of course, very numer- 

 ous, but they do not call for any special observations. They 

 present the usual varieties of size and form. 



Though less numerous than the flakes, the scrapers* are still 

 very abundant. On the whole they seem to me longer and 

 narrower than the usual Danish type. Some of them were 

 probably intended to be used in the hand, as both ends are 

 fashioned for scraping. These may be called double- scrapers. 

 Others were apparently fixed in handles, as the end opposite 

 to the scraper is broken, sometimes on one side, sometimes 

 on both, so as to form a tapering extremity, which may have 

 been fixed in a handle either of wood, bone, or horn. Many
