Well, I put my new mule in the harness for the first time since he came here, and I have to say, he's a smart one. I've fooled with him quite a bit since I first got him, and he's improved a heck of a lot. He was promised "broke single and double, will ride and work well, catches and handles easy." And he did til the previous owner was out of sight. But, that's no big deal, really. When I first put him in the barn, he flew into kicking and really worked my old mule over with those back feet. So, I said old boy, I know how to straighten that out. I put him in with my mare mules and after they had a go at him, he's never offered to kick anything else, and now he's a perfect gentleman around all the rest of the herd. After a while longer fooling with him, I can whistle in the morning and he comes right to the gate, puts his head in the halter and is ready to come to the barn. Some mornings, if I have my hands full, I can open the gate and turn him out in the yard, and he will follow me to the barn and go to his stall. He does, now, stand perfect for shearing, harnessing or what ever I choose to do with him and doesn't mind having his ears handled. So, back to his first time in harness for me. Ground drove him a little in the round pen, and everything went fine. He knew gee, haw, back and whoa. Did everything just fine, so I opted to take him out for ground driving in the driveway and pasture. We turned from the hitching rail and started down the drive, got about 20 feet and he went sideways and wanted to turn back. Got him lined out to go on and he did, but he wanted to go at a run. I reminded him he had a bit in his mouth with a few bumps and lightened up as soon as he slowed to a walk. We made a few more passes and he forgot what "gee" meant. He'd give me his head to the right, but then run through his shoulder to the left. So, I managed to let the lines drop down his hip so I could use him for leverage and stay behind him, and we went in a few circles, before he stepped to the right. He managed to bump into the wagon, walk backward over a sled, and back into the barn wall, before stepping out like he should. I noticed though that each of these bumps were done pretty lightly and corrected pretty quickly, which told me he wasn't serious about getting away, he was just checking to see if I as serious about what I was asking. He put me through about every test he could think of that day, but we still ended on a positive note and I've established ( I think anyway) that he doesn't trust me, and doesn't really know me yet, and we're gonna have to spend a lot more time at the basics before he sorts out what he can and can't do. Of course if I keep getting behind I may have to hook him with one of my bigger mules and let him have a go on the disc harrow. I think he's a good mule at heart, he just needs to learn I ain't such a bad guy either.
