Gum Arabic: Tapped from the Acacia, Dried in the Air
Gum arabic is the hardened gum that oozes from gum acacias. Strip small pieces of bark from the branches and a clear mucilage oozes out, hardening in the air into rounded tears. Andrew Ure (1839) notes gum Senegal was gathered in November; the tears dissolve in water and bind watercolours and inks.
The picture: raw gum arabic tears of different grades and the ground powder.

Pick and sort
Pick the hard tears into a basket. Spread them on mats in the sun, which bleaches them (Ure), and sort out bark and dark pieces; the clearest, palest tears are best.

The tears are brittle: crush them in a mortar and sift for a powder that dissolves quickly. Keep in a dry, closed jar.

Tapping and the gum's properties are from Wikipedia and Ure; the sorting and the solution strength are ours. The sources give no fixed waiting time between tapping and picking.
