ROUTINE 199 



attracted to the wetted stick, because both have 

 ascending capillary curves applied to them. The 

 water-repelling surface, which best resists drying, is 

 turned outwards and exposed to the air. Duckweed 

 clings to the legs of water-birds and to the elytra of 

 water-beetles, and may be carried by them to distant 

 pools. The wide distribution of the various species 

 and the extraordinary speed with which they over- 

 spread any water-surface to which they may get 

 access, are due among other things to the capillary 

 forces which come into play at the surface of any 

 liquid. 



ROUTINE. 



The course of the year admonishes every man who 

 takes life seriously to attend to his daily routine. 

 Life is a long year ; the year is a long day. 



Here are three maxims by Lagrange, which I 

 venture to recommend to every student. The first was 

 borrowed from the practice of Frederick the Great. 



1. Do the same things at the same hours every 

 day, taking the hardest first, if possible. 



2. Before going to sleep settle the plan of the next 

 day's work. 



3. When you read for study, read pen in hand. 



To these I will make bold to add another. After the 

 morning bath encourage the circulation by running till 

 you are out of breath. A strong young man will 

 easily run a mile, but those who are older or less fit 

 should only attempt what they can do without 

 distress.
