Dr. A. S. Alexander, the writer and compiler of “Horse Secrets,” has had upward of 25 years’ experience in matters pertaining to agriculture, horse breeding, veterinary science, press writing and teaching. He was the author of the first stallion service legislation and inspection regulation in America, the first law of the kind having been written by him and enacted by the Wisconsin Legislature in 1905. Similar legislation now is in force in some 16 other states, and it is accomplishing much for the improvement of horse breeding. Horse trading offers unusual opportunities and temptations for sharp practises. Both buyer and seller equally need to be horse-wise and alert. Dishonesty is discountenanced in the great horse markets, but it is common among scalpers, “gyps” and small traders outside of the recognized markets and is likely to be practised by either the buyer or the seller. The items published in these pages disclose many sharp practises which, aside from their interest as facts not generally known, are valuable as information for the man who would engage intelligently in horse buying and selling. The writer and publishers of this book desire to expose these tricks, and to decry their practise in the markets and among outside dealers and breeders. “Forewarned is forearmed,” and the information here given will doubtless save many a man from loss, and tend to make dishonesty less rife because less likely to succeed. In mentioning the various tricks herein disclosed, the exact methods have not been given in detail. We have no desire to instruct readers so that they may “go and do likewise”; for the same reason doses have not been given for the administration of the various drugs and “dopes” used by tricksters.
