These examples should not, however, lead one to believe that all 

 these moderately large scraper-knives or others were hafted in this 

 manner. Manj- examples have been found in situations which, by 

 the accompanying relics, are proved to be not old enough for the 

 cement to have crumbled away from the action of time. A good 

 instance of this contention are the objects represented in Fig. 137, 

 and the tools used for producing the same. We can date the intro- 

 duction of gun and spade in the district when the examples come ; 

 and so recent is it that it is impossible that the gum-cement should 

 not have been preserved had the small tools been hafted.
