NATURE OF INDOOR-WORK. GEOLOGICAL SECTIONS 



N a geologist returns to his quarters after a long day 

 in the field, if he means to make further use of the in- 

 formation which he has collected in the course of his 

 walk, he ought on no account to allow himself, no matter 

 how seductive may be the attractions of his comfortable 

 re, to dismiss from his mind the labours of the day 

 until he has looked over his notes, and filled in, while 

 still fresh in his memory, all details which he did not 

 find time to jot down on the ground This task some- 

 times demands not a little self-denial on the part of one 

 els th.a he has worked well and earned his ties/a 

 with a pleasant book or the latest newspaper. But it 

 must be done, and done then. Put off till next evening, 

 the duty is more irksome, and the details are already 

 beginning to be elbowed out of memory by the host of 

 new ones which have in the interval been observed.
