Instructions for weather-proofing a wooden roof after a method used in Sweden.
Communicated by the Royal Society of Sweden, to that of London.
--------------- After roofing a house with wood, boil tar in a kettle, and
mix finely pulversed charcoal with it, till it is of the thickness of mortar;
bread this with a trowel about a fourth of an inch thick, over the roof; it
[w]ill soon grow hard and defu the vicissitudes of weather. Roots thus
[co]vered, have stood in Sweden above a century, and still want no repair.
