Note 622 — Chapter XXXVIII · TRAINING THE PASSAGE SAKER TO COMMON CRANE
D. C. (Douglas Craven) Phillott translation
Salaf, a word explained by the author in a marginal note to mean bi-duzda, “secretly.” Apparently by this term the author means that a solitary half-tame crane must be stalked when feeding and the hawk allowed to bind to it on the ground.
