Owing to the kindness of the India Rubber, Gutta Percha, and Telegraph Works Company of Silvertown, and especially of their engineer-in-chief, Mr Robert Kaye Gray, I was enabled to accompany their expedition for laying the telegraph cable between Cadiz and the Canary Islands. It consisted of two steamers belonging to the company, the “Dacia” and the “International”; and I was allotted a place and all facilities for working on board the “Dacia,” where Mr Gray had charge. I joined the expedition at Cadiz on 3rd October 1883.
