From the Niagara Falls Review:
He was, the local press marvelled, “by far the most intrepid performer who ever dared the rocks and rapids of the Niagara River.”
This lavish praise was directed to Clifford Calverley, a talented tightrope walker who had dazzled a huge crowd with his expertise on the wire. The performance took place on the afternoon of Wednesday, Oct. 12, 1892. Calverley’s wirerope, 2.5 centimetres thick and 273 metres long, was stretched across the Niagara River gorge a short distance upstream from the Railway Suspension Bridge, which stood where the Whirlpool Rapids Bridge is now.
Calverley was not the first tightrope artist to perform at Niagara Falls. He was, in fact, the eighth, the first being the great Blondin who was here in 1859 and 1860. However, he soon showed his ability on the wire was as good as any of his predecessors.
