If you desire, tell below in five or less words announcer tor whom you have cast this ballot: what you most like about the GOLD CUP STANDING CHANGES SLIGHTLY WITTEN IN FOURTH PLACE; 2-LO NOW IN CONTEST Leaders Now Eighteen Votes Apart; Three Names Added to List; Two More Ballots ■With only two more ballots to go, the votes are beginning to come in in large numbers. George Hay, WLS, still holds the lead, with his namesake — no relation whatsoever — Bill Hay, KFKX, only eighteen votes behind, pushing him hard. Three new members have jumped up into the list of leaders during the week, and each one wishes to state that he is a strong antagonist; one who has to be reckoned with when it comes to the finalshowdown. They are as follows: Jerry Sullivan. WQJ, who now has 68 votes; C. W. Kirby, WWJ, 53 votes, and last but not least, Art Burroughs, 2-LO, London, England, with 52 votes. English Announcer Enters Art Burroughs is the only, announcer among the leaders who hails from outside the United States. Announcers have been nominated in Porto Rico, Mexico and Cuba, but they are not yet among the leaders. Another nominee who has jumped ahead is J. XL YVitten, WOS. Last week he was in' fifth place, but now he is in fourth place, while the Hired Hand has taken Witten's former position. No more new nominations have been received, and from the looks of things any announcer who is not listed had better step lively. Sixteen consecutive ballots entitle the holder to a bonus of seventy-five votes bf-side the sixteen for the original ballots. While twelve consecutive votes are given a bonus of fifty votes. Remember this when sending in votes and get as many in succession as possible, thereby getting the benefit of the additional bonus. Don't forget that all votes must be in the mail by September 8, at the latest. Any votes mailed after this date will not be eligible toward your favorite announcer. When the final result is published, we will also tell Just what requirements are desirable for an announcer to have. This will be the consensus of public opinion taken from the ballots received.

This material is said to be the same as the compound formerly used in the oldfashioned black inks made of iron and oak galls. The solution of iron and gallic acid is a colloidal solution, which means that it contains innumerable tiny particles, finer than the smallest specks of dust. These particles are said to carry the currents through the tube just as the electrons do in the ordinary vacuum tube. The tube contains the usual three electrodes, corresponding to the filament, the grid, and the plate. It is unnecessary, however, for the filament electrode of the new tube to be heated or to serve as a source of electrons. No A battery is necessary, although the high voltage B battery is used as in ordinary tubes. It is said that the new solution of iron and gallic acid is a great improvement over the colloidal solutions used in previous liquid-filled detectors, which solutions were mainly either silver or sulphur. Experimenters are reported to be enthusiastic over the behavior of the new iron and gallic acid tubes, especially when used as detectors for the reception of local stations.

Address City State 65 This three tube receiver Is built to give the efficiency of a five tube set. It represents the triumph of excellence In the radio field. The first tube furnishes non-reradiatlng, non-oscillating radio frequency amplification. The second tube Is a regenerative detector and further is so coupled up as to reflex back on the first tube for one stage of audio frequency amplification. The third tube furnishes a second stage of Audio frequency amplification. Thus the three great powers in radio, represented by the three "B's," Itadio Frequency' Regenerative, and Reflex, give both the name and the wonderfully efficient performance to the Crosley Trirdyn 3R3.
