Their hammers must be quite even & polished, and if in some unfortunate case the rust, the or some other use, has damaged them, they first polish them with emery stone powder, then they finish burnishing & smoothing with the putty. Otherwise they would not strike neatly. It is also necessary that the face of the anvils be the same.

A new vine

When the vine has taken root well, if you want it to grow many cordons, having dug furrows next to it, put two handfuls of pigeon guano next to each rootstock.

Colored water

Distilled urine, distilled vinegar and eau—de—vie take on a blue and green color from powdered and finely ground burnt bronze. And the residue from this tincture will be red copper if you distill the things indicated with a filter.

Varnish resistant to water

Flanders varnish, made with turpentine & oil from this or from mastic, can come off and does not hold up in the rain. But that made with huile de noix blanche, as you have done, holds in the rain and is very clear & beautiful & dries soon. This is why one uses this one for painted banners & signs that one carries in the rain.

Fruit made from sugar
