They will probably have a far more difficult task than ours, but I do not 

 think it fair to condemn them to spend part of their time in a preliminary 

 and possibly fruitless search for tools which we have forged and hidden. 



' As one lamp lights another, nor grows less,' Science of to-day will 

 partly fail in its clear duty if it fails to pass on to to-morrow any of the 

 knowledge which it has been privileged to acquire, or if it forgets that it is 

 for to-morrow, rather than to-day, to assess the true value of to-day's 

 success and failure.
