Take a piece of very clear ice and melt it down into the hollow of your hands so as to form a large lens. The illustration shows how this is done. With the lens-shaped ice used in the same manner as a reading glass to direct the sun's rays on paper or shavings you can start a fire. - Contributed by Arthur E. Joerin.
“Are you dejected? here is comfort. Are you sinful? here is righteousness. Are you led away with present enjoyments? here you have honours, and pleasures, and all in Christ Jesus. You have a right to common pleasures that others have, and besides them you have interest in others that are everlasting, that shall never fail; so that there is nothing that is dejecting and abasing in man, but there is comfort for it in Christ Jesus.”
–Richard Sibbes, Description of Christ
