EXPLORER’S DEATH
Funeral of Surveyor J. A. Mahood Takes Place Today, The funeral of J. A. Mahood is taking place this afternoon from the residence of his sister, Mrs. Berkley, Burdett avenue, and from Christ Church cathedral

The deceased was a native of St. Andrew’s, N. B., and has been engaged during the greater part of his active life with exploring parties. He served with the surveying party which prospected the proposed line across the continent from the Atlantic to the Pacific, thence up the coast to Alaska, across Behring Straits and through Siberia to the various parts of Europe. The scheme was never put into practical form.

Mr. Mahood served as major in the surveying party which had the Siberian portion of the survey to make. Upon the abandonment of this work Mr. Mahood returned to America and was engaged for a time in making surveys for the forts of San Francisco bay.

in 1872 he came to British Columbia and followed his profession in the survey works of the province.

By 1892, Mahood had cut a trail past Indianpoint Lake on his way to Tête Jaune Cache, where he was to meet the Thompson River party of Alfred Richard Cecil Selwyn [1824–1902]. A few months later the CPR chose a route far to the south and the trail fell into disuse.
