On this occasion Mr Park has brought with him a De Forest wireless telephone of the type adopted by the American Navy. The advantages of the system are obvious; and it is probable that many of the mines in the outside districts of the Transvaal may find the idea of considerable utility to them. Another invention, for the first time introduced to the Rand by Mr Park, is an automatic recording telephone, which takes and keeps a record of all messages received. The utility of this idea is also plainly evident; and Mr Park is to be congratulated on his enterprise.
