HUNGER AND FATIGUE. Al 
quires no comment. In walking under a hot sun the head 
may be sensibly protected by green leaves or grass in the hat; 
they may be advantageously moistened, but not enough to drop 
about the ears. Under such circumstances the slightest giddi- 
ness, dimness of sight, or confusion of ideas, should be taken 
as a warning of possible sunstroke, instantly demanding rest, 
and shelter if practicable. uncer and Fatigue are more 
closely related than they might seem to be; one is a sign that 
the fuel is out, and the other asks for it. Extreme fatigue, 
indeed, destroys appetite; this simply means, temporary inca- 
pacity for digestion. But even far short of this, food is more 
easily digested, and better relished after a little preparation 
of the furnace. On coming home tired it is much better to 
make a leisurely and reasonably nice toilet than to eat at 
once, or to lie still thinking how tired you are; after a change 
and a wash you will feel like a ‘‘new man,” and go to table 
in capital state. Whatever dietetic irregularities a high state 
of civilization may demand or render practicable a normally 
healthy person is inconvenienced almost as soon as his reg- 
ular meal-time passes without food ; and few can work comfort- 
ably or profitably fasting over six or eight hours. Eat before 
starting ; if for a day’s tramp, take a lunch; the most frugal 
meal will appease if it do not satisfy hunger, and so postpone 
its urgency. As a small scrap of practical wisdom, I would 
add, keep the remnants of the lunch, if there are any; for 
you cannot always be sure of getting in to supper. StimuLa- 
TION: When cold, fatigued, depressed in mind, and on other 
occasions, you may feel inclined to resort to artificial stimulus. 
Respecting this many-sided theme I have a few words to offer 
of direct bearing on the collector’s case. It should be clearly 
understood in the first place that a stimulant confers no 
strength whatever; it simply calls the powers that be into 
increased action at their own expense. Seeking real strength 
in stimulus is as wise as an attempt to lift yourself up by the 
boot-straps. You may gather yourself to leap the ditch and 
you clear it; but no such muscular energy can be sustained ; 
exhaustion speedily renders further expenditure impossible.
