If you have lost your bearings and it is a cloudy day, put the point of your knife blade on your thumb nail, and turn the blade around until the full shadow of the blade is on the nail.  This will tell you where the sun is, and decide in which direction the camp is.

Points of Compass

Face the sun in the morning, spread out your arms straight from body.  Before you is the east; behind you is the west; to your right hand is the south; to the left hand is the north.

A Home-made Weather Prophet

For a home-made barometer you need a clean, clear glass bottle.  Take one drachm[1] each of camphor gum, saltpetre and ammonia salts, and dissolve them in thirteen drachms of pure alcohol.  Shake till dissolved.  Then pour in bottle and cork tightly.  Hang the bottle of mixture against the wall facing north, and it will prove a perfect weather prophet.  When the liquid is clear it promises fair weather.  When it is muddy or cloudy it is a sign of rain.  When little white flakes settle in the bottom it means that the weather is growing colder, and the thicker the deposit the colder it becomes.  Fine, starry flakes foretell a storm, and large flakes are signs of snow.  When the liquid seems full of little, threadlike forms that gradually rise to the top, it means wind and sudden storm.

Plant Barometers

The dandelion is an excellent barometer, one of the commonest and most reliable.  It is when the blooms have seeded and are in the fluffy, feathery condition that its weather prophet facilities come to the fore.  In fine weather the ball extends to the full, but when rain approaches, it shuts like an umbrella.  If the weather is inclined to be showery it keeps shut all the time, only opening when the danger from the wet is past.
