The need for exploration of unsettled areas of Vancouver Island had been the subject of comment in the colonial press in the early 1860s but it was not until the new Governor, Arthur Edward Kennedy arrived in March 1864 that the project had a sponsor.
From his arrival in Victoria in May 1863, Robert Brown had been working in the colony as a seed collector for the British Columbia Botanical Society of Edinburgh on a meagre income.
In September 1863 he travelled to Lilloett and New Westminster followed by a return trip to Port Alberni where he established the length of Great Central Lake.
[3]: 4–6 Although his seed collection disappointed his sponsors, the experience and the reputation he earned in Victoria was recognized on June 1, 1864 when he was appointed as commander of the Vancouver Island Exploring Expedition.
Brown considered his mission to report on the topography, soil, timber and resources however his sponsors were more interested in whether gold would be found.
Following the resignation of John Foley, the VIEE Committee on July 30 decided that "two efficient miners" should be appointed as replacements.
The other, led by Brown, followed the Nitinat River to the west coast to meet the Leech party at Port San Juan for fresh supplies which were to be brought in by boat from Victoria.
After exploring in that area, they crossed the island to the Qualicum River and then travelled by canoe to Nanaimo to board the Grappler.
When Brown explored up the island in August 1864, he found the trail blocked by windfalls and washouts, although he did find one bridge remaining at the Qualicum River.
