Make Newspaper Logs

A number of companies now market machines designed to help you roll your family's old newspapers into "logs" that can be burned in a fireplace or stove. After testing a couple of these devices, I think the idea is a good one for two reasons: it puts recycling on a real grassroots basis by allowing you to directly convert part of your waste into something useful and it gives you a small, partial answer to today's fuel shortage.

There's no need to shell out good dollars for a "log rolling" machine to realize these benefits, however. Just get yourself a length of old broomstick and start tightly rolling one section of a sheet of newspaper after another. When the "log" is about two inches thick, slip the broomstick out, tie the bundle with light wire, and soak the paper in one pint of charcoal lighter or kerosene ( never gasoline). If you have no other soaking tray, you can make one that will last for years from a sheet of heavy-duty aluminum foil.

Once the rolled paper has soaked up the fluid, wrap more waste newsprint around the saturated core .. enough to make a log about 4-to-5 inches thick. Tie the bundle with light wire and set it aside. Three of these logs will burn all evening in a fireplace.

How to Determine Relative Humidity

The relationship between the maximum amount of moisture that the air can hold and the amount of moisture that it actually does contain is called relative humidity. (And we all know — or should know — that the moisture in the atmosphere during the summer makes us swelter quite as much as the heat in the air, just as lack of humidity during the winter can make a room feel much colder than it actually is.)

To measure relative humidity, obtain two identical thermometers and completely wrap the bulb on one with a small square of wet muslin. Tie the soaked fabric on with thread and place both thermometers in the breeze from a fan. Check the instruments after one to two minutes, note the reading of each (the wet-bulb thermometer will register somewhat lower than the dry) and compute the relative humidity on the chart in the Image Gallery.
