QUOTES BY FRIEDRICH VON KRANE
On Auxiliary Reins

"To sum up the application of the auxiliary reins: The master will use these instruments with due caution during the training process only if saving his own energy makes them desirable. The novice should never use them right away for training purposes. Instead, he should try their effect on a well trained horse first, in order to harmonize his aids with the altered effects on the horse. For a while, trainers liked to amass auxiliary reins of all kinds, so that their riding looked liked playing the organ, as they were pulling this register and that. The most common consequence of their excellent art was that the horses had as many bad habits as auxiliary reins! In a squadron I would allow an auxiliary rein only as an exception, even for training purposes. Auxiliary reins are usually just lazy servants that help to produce a superficial impression and support other lazy-bones in loafing."     (1856)
