Elizabeth Karr, The American Horsewoman
“ Too tight a girth is injurious to the horse, but too loose a one may cause the saddle to turn. A round, plump horse with low withers will need tighter girthing than a better shaped one. The lady rider should study the shape of her horse, and use her own judgment as to how tight the girths should be drawn, making due allowance for the trick alluded to above. If there is any second person present while the saddle is being arranged, matters may be facilitated if this person will hold the saddle firmly by the off-pommel while the girthing is being done. ”
