THE DOUBLE DANGERS OF DIRT AND DAMP.

Few, if any of us, after installing our first radio receiver have been content for long after the mere knowledge that, by pressing a switch, noiss of sorts emanates from the loud speaker or head-phones.

Wireless, to a more marked de gree than its fellows in modern ience, the auto or gramophone, has a fascination to the even un- scientific mind that demands deeper understanding of the "why's and wherefore's," Thus it is that to-day we have people of all classes and callings discussing intimate details of this entertaining science.

From the owner of the modern crystal set (of little use in Hong Kong by the way) to the more ad venturous ether-searching owner of a super set, from the schoolboy to the professor. the peculiarities of the pentode" and the "idiosyn cracies of the ether provide topics of never-flagging interest

It is possible that this enthusiasm on the part of the set-owners is apt to deter many would-be owners by creating the impression that some rudimentary knowledge at lenst is required to work the

machine:

That this is an error is evidenced as any wireless dealers, the modern trend of radio design being of the simplicity type. requiring little more skill in operation than the gramophone.

The owner of such a set, however, soon gets more adventurous and, having heard that a neighbour with

Red Seal Recordings

One of the host masterly Victor Records of all time is Bloch's Concerto Grosso, which Fabien Sevitzky and the Philadelphia Chamber String Sinfonietta have recorded for release this month. Here is music that vitalizes the powers of the small string orchestra to the utmost; here is a recording that couples high genius with flesh-and-blood reality! To keep it company is a truly inspiring and entirely complete recording of The Pirates of Penzance, performed by the Rupert D'Oyly Carte-Light Opera Company and Orchestra. Crystal-clear diction, bright and sparkling interpretation, place this album of Victor Records among the beat within recent times. There are a large number of other Red Seal Records which you will want to hear and keep forever. You are cordially invited to hear them on our Victor Radio-Electrola.
