The symptoms of lice are these: the feathers on the back of the neck stand erect, and the hawk is ever scratching her head with her foot and picking at her back and breast, with her beak: she is never at rest. Treatment: get some quick-silver and “kill”[716] it with vinegar; then apply it to a thread and cast the thread on the neck of the hawk, and the lice will be destroyed.[717] Item: take tobacco-water and mix therein a little salt, and apply the mixture to the back of the neck and to the loins, and she shall be free. Item: there is in Mazenderan a grass called kankarvāsh: pound some of this very fine and mix therein a little wine, and apply to the back of the neck and under the wings, and to every place where you know the lice collect and hold their councils. Apply this and the lice will instantly fall off. Item: place your hawk in the sun, and as soon as she is warmed, the lice will collect on the large broad feathers, three on each side, called by the Kurds yār māliq.[718] You can then remove the lice with scissors. Item: take Armenian bole,[719] country tobacco-leaf and good cigarette tobacco;[720] grind and mix. By means of a reed, blow this powder on to and into the feathers. Then place the hawk in the sun for a little, and the lice will disappear. Item: take some carded cotton-wool and twist it into a roll as thick as your finger, and at night cast it on your hawk’s neck and put her in a warm place. All the lice will collect on the wool. In the morning snip off the wool hastily and cast it away.
