And he wandered away and away 
With Nature, the dear old nurse, 
Who sang to him night and day 
The rhymes of the universe. 
And whenever the way seemed long, 
Or his heart began to fail, 
She would sing a more wonderful song, 
Or tell a more marvellous tale. 
EXPLANATION OF PLATE IX. 
The plate is designed to show the set of things that may always, or 
nearly always, be collected at the temporary halting-places of early races of 
mankind. They consist of implements («) with a true wavy, and therefore 
cutting edge, very different from the similarly shaped stone ( b ) which has a 
crushed edge, and is therefore either a forgery or has been the result of 
accidental and not intentional shaping. The flakes (c) may either be 
triangular or rhomboidal in section, and, like these two, unworn, having 
been merely knocked off in fashioning a tool. But they may on the other 
hand have been used for work, and then the marks of true wear ( d ) will be 
distinguished from the u crush ” wear (e) by being on one side of the edge 
rather than on both. The cores may be of different shapes (as /, g, h , «), 
while those with lower angles, produced as in the “hoof” cores ( h ), or (*') by 
striking off a fragment of flint after the corehas been made roughly cylindrical, 
frequently bear marks of wear as if they had been employed as rough 
chisels. The briquets ( k ), or strike -a-lights, are thick oval pieces of flint, 
with, one edge worked somewhat round, and one side nearly flat. It is 
on tbis, that the material used as tinder is held. Some of the irregular 
pieces ( l ) have a rough cutting edge on one side only, the other being left 
round so as to be held in the hand, while many flakes are worked for special 
purposes, such as long “ thumb scrapers ” for skin-dressing (m), notched 
scrapers (n) for arrow-fashioning, piercers or rimers (o) for making the eyes 
in bone needles, and circular scrapers (p), which are large oval pieces of 
flint much thinner than a briquet, but bearing marks of wear all round. 
There is not much difference between these two forms, save that the scraper 
being thinner is better calculated for the work.
