Messes Dicksons & Co., Nurserymen and Seedsmen, Edinburgh, have established telephonic communication between their seed warehouse in Waterloo Place and their Pilrig Park Nursery, Pilrig Street - a distance of fully a mile. The instrument they have adopted is Crossley's Patent Transmitter, which is one of the best for using in towns, where the noise from the street traffic renders the ordinary telephone of little practical value. It must prove highly advantageous to Messrs Dicksons & Co., bringing as it does the two branches of their business into instant communication. So far as we know, this old established firm is the first in the trade that has taken advantage of this recent invention.
