Directly across from my home was a busy smithy. Watching horses beeing shod is a truly interesting process, since every horse has different size feet ! Now we go to a shoe shop and try on an 8 or an 8½ wide or narrow. When the horse comes in, the farrier takes off the old shoe and might need to take one of his stock and make it wider or narrower by heating and hammering it to fit. (see next story) Of course this means a lad sees big BIG animals, the furnace and the metalwork all in one place. I spent many hours watching and the horses seemed quite happy about it all.
