photographs whilst travelling in the remotest areas of the Himalayas and working under the most exacting physical conditions, places him firmly amongst the very finest of nineteenth century travel photographers. On 29 July 1863, he left Simla on the first of his three major Himalayan photographic expeditions. With a retinue of some 30 porters to carry his equipment, he travelled across the Simla Hills to Chini, in the Valley of the Sutlej River, 160 miles north-east of Simla, and spent some time photographing in the Chini-Sutlej River area, before heading up to the borders of Spiti, and returning to Simla on 12 October 1863, with 147 fine negatives. In the following year, Bourne set out on another major trip, this time a nine-month trip to Kashmir. Leaving Lahore on 17 March, he journeyed north-east to Kangra and from there, via Byjnath, Holta, Dharmsala and Dalhousie, to Chamba. From there, he went on to Kashmir, arriving on the borders on 8 June; by the middle of the month had reached the Chenab Valley. The following weeks were spent photographing the scenery of Kashmir before proceeding to Srinagar, where he stopped for some weeks, sight seeing and photographing before continuing his journey on 15 September. The return journey took in the Sind Valley, Baramula, Murree, Delhi and Cawnpore (now Kanpur) before arriving in Lucknow on Christmas Eve 1864. Bourne's third and last major trip was perhaps his most ambitious; consisting of a six-month journey in the Himalayas with the goal of reaching and photographing the source of the Ganges. He left Simla on 3 July 1866, in the company of Dr. G.R. Playfair (brother of the famous English politician Dr. Lyon Playfair), and travelled with him through Kulu and Lahaul, over the Kunzum Pass into the Spiti valley, where they later parted company. Bourne then continued on alone (except for his forty porters!); over the Manirung Pass, where he took spectacular views of the 18,600 foot high pass; which held the record for the highest altitude photographs that had yet been taken for twenty years. Thence, down to the junction of the Spiti and Sutlej Rivers and on to Sungnam and the Buspa Valley. He then climbed up over the Neela Pass, and down into the Upper Ganges Valley, where he journeyed on up to the Gangotri Glacier. There he went on to photograph one of the prime sources of the Ganges,
