Vevey, Clarens and Chillon were familiar to Byron from his previous boattrip with Shelley, but on Thursday 19 September he and Hobhouse set out for what was new territory for them both. They were using a well-known guide book for travellers in Switzerland by Johann Gottfried Ebel, a French translation of which Hobhouse had acquired before he left England. The route they followed roughly corresponds to what is tour number 33 in Ebel and they both gave day-to-day accounts of it, Hobhouse in his diary and Byron in a long letter he wrote to Augusta in diary form. Sending Joseph and the char-à-banc on the easier road which passes through Bulle to the lake of Thun, they themselves (accompanied by Berger and a local guide) tackled the mountainous country behind Montreux on horseback, climbing steeply through the villages of Chernex and Les Avants until they reached what is known as the col de Jarman. Byron was surprised there by just how high in the mountains there was pasture for cattle. He was enchanted by the constant noise of cow bells with which he was then surrounded, and by the sounds of the shepherds (as he describes them) calling to each other on the crags above, or playing their pipes.
