A treatise on the origin, progress, prevention, and cure of dry rot in timber

by Thomas Allen Britton

TO PREVENT WORMS IN TIMBER.

1. Anointing with an oil produced by the immersion of sulphur in aquafortis (nitric acid) distilled to dryness, and exposed to dissolve in the air.

2. Soaking in an infusion of quassia renders the wood bitter.

3. Creosoting timber, if the smell is not objectionable.

4. Anointing the timber with oil of spike, juniper, or turpentine, is efficacious in some degree.

5. For small articles, cover freely with copal varnish in linseed oil.
