Off the DEEP END Christopher Morley RADIO BROADCAST ADVERTISER XT . . . "No one doubts the amazing vivacity and facility of Christopher Morley . . . 'Off The Deep End,' like several of its predecessors is a collection of stray pieces, short stories, brief playlets, humorous squibs and Lambsian essays. The reader saunters, so to speak, through Mr. Morley's engaging purlieus admiring the gusts of the greenery, the sparkling quality of the streamlet of wit and the whimsicality of the curious growths" — New York Times. . . . "Whatever he does will be fascinating talk . . . talk which makes his book of essays a pleasant adventure" — New York Evening Post. . . . Other books by Christopher Morley. the Romany STAIN, WHERE THE BLUE BEGINS, THUNDER ON THE LEFT and THE HAUNTED BOOKSHOP. DOUBLEDAY DORAN 8C COMPANY, INC. Garden City, New York #2.50 at all bookshops A RADIO RECEIVER IS LIKE A CHAIN... A CHAIN of parts, if you please . . . transformers, tubes, condensers, resistances and the like as links of the chain. Unless each link performs to perfection the whole receiver is condemned and your name with it. A lot of grief can be traced to one little part . . . the volume control. Noises are set up . . . uneveness of control develops . . . locals are hard to handle. You can save yourself plenty of trouble by seeing that the name "Centralab" is stamped on the volume control. The Centralab exclusive rocking disc construction prevents any change in the resistance or the development of noise. Centralab controls give a perfect control of all stations with an even, "velvety" smooth action. This shows the exclusive rocking disc construction of Centralab volume control.* "R" is the resistance. Contactdisc "D" has only a rocking action on the resistance. Pressure arm "P" together with shaft and bushing is fully insulated. This is the action of the usual wire wound control after it has been in[ use for some time . . . like dragging a sticktover a cobblestone pavement. CENTRAL RADIO 20 Keefe Ave. JLAB ORA.TO RI E S Milwaukee, Wis. The tailor uses the same principle as CentralaV He does not want to ruin the garment by placing" the iron on it so he places a cloth in between. Centralab controls cannot ruin the resistance because the rocking disc is in between the pressure arm and the resistance.
