antique books horse training & care, Prof Beery Mail Course in Horsemanship early 1900s vintage

Lot of four small softcover books from Professor Beery's mail order Course in Hosemanship.

These are books number 2, 3, 4 and 5 NO BOOK NUMBER 1, but it looks like each book is complete in itself. All are worn, and marked with the name of a former owner.

These have great cover art and engraving style illustrations, from a time when a good horse was the hot rod of the day. Very interesting reading!
