For out-door work he used the following:
Rosin, four or five parts.
Bees-wax, one and one-half to two parts.
Linseed oil, one to one and one-half.
This is made into a mass to be applied by hand. A very pleasant and neat mode of using the wax is to pour it when melted, upon thin muslin or strong paper, and spread it thin with a spatula. The tissue is then cut into strips of convenient size. The application to cotton yarn for root-grafting, has already been mentioned.
The French use the preparation given below, sufficiently warm to be liquid, but not so hot as to injure the tissues of the tree, and apply it with a brush:
| Black pitch | 28 parts. |
| Burgundy pitch | 28 parts. |
| Bees-wax | 16 parts. |
| Grease | 14 parts. |
| Yellow ochre | 14 parts. |
| Making | 100 parts.[14] |
Mr. Du Breuil also refers to Leport's liquid mastic in terms of commendation, but speaks of it as a secret composition.
Downing recommends melting together:
| Bees-wax | 3 parts. |
| Rosin | 3 parts. |
| Tallow | 2 parts. |
He says, the common wax of the French is
| Pitch | one-half pound. |
| Bees-wax | one-half pound. |
| Cow-dung | one pound. |
