I've just been delving about in my library and dug out a couple of books on droving in Britain, these are:

'The Drovers, who they were and how they went: an epic of the English countryside' by K.J.Bonser, MacMillan & Co. Ltd., 1970.

and

'Highland Drove' by John Keay, John Murray Ltd., 1984

The latter book is the author's account of an attempt to recreate a Highland drove in 1981. "John and Julia Keay attempted to recreate the most dramatic and demanding of these droves. With assorted friends, dogs and ponies they set off from the west coast of the Isle of Skye to drive a herd of Highland cattle two hundred miles to Crieff in Perthshire."
