Before you know it this book will be sold out, since the earlier volume, Riding and Schooling Horses lost no time in soaring to a premium -- so before you do anything else, look up your customers to whom you sold volume I. Then look up your Derrydale collectors, the people who are as interested in collecting as in subject matter. While the former book dealt with training the rider to a sound forward seat, this turns to the horse and his training -- as Chamberlin says with no apologies to Mr. Wiggin ""The marks of an educated horse!"" Here we have the American cavalry methods based as they are on the best of all the foreign schools, especially Saumer in France. Colonel Chamberlin has been sent to study the various systems and has represented us in the Olympics.
