A question was posted on another board regarding in camp provisions for securing horses. The following is the advise I gave, but I was wondering from anyone who has historical packing experience if there was more to learn.
high and short" anytime they are "secured". As Creek suggested a high line tied between trees, tight enough that they don't slide down the rope and get tangled with other stock. High and short enough that they are able to graze and get tangled up. Under the right circumstances "Big open meadow" a lead mare can be picketed and the other (especially mules) can be turned loosed and usually hobbled. The herd won't want to stray far from the mare.....this doesn't work so well with animals that are not pastured together. However picket line works best with a single leg hobble rather than tying to halter. Biggest issue with picketing at night is that the horse/mule doesn't get rope wrapped around a leg and get rope burn or cut. There are modern ways to avoid this, but in a historical context you're generally better off securing to a high line at night and hobbling when grazing. Night time grazing also works best if your camp maintains a night watch. The last historical night camp I had I took in a team of Percherons. The mare was picketed and the gelding was hobbled. But everyone (except me) took an hour of watch throughout the night. First time in Grizzly country I was able to let my stock graze through the night and not worry about them".
