Extract

In 1892, I suggested that communication could be established between ship and ship by means of coils, and as a trial of the system on a large scale has recently been made with the view of establishing communication between North Unst lighthouse, situated on Muckle Flugga, and the mainland (fig. 1), thence to the lighthouse station at Burrafiord, a distance of two miles, a record of the trials may be of interest to the Society.
