Electrician and Mechanic, October, 1908, page 179:

        This department is devoted to the Club members and those interested in Wireless Telegraphy.  We will publish experiences, discoveries, and suggestions, which may be helpful to all interested.

    I WISH to state that, as one of your subscribers to ELECTRICIAN  AND MECHANIC, I have been thoroughly pleased with the articles in your magazine of the past few months, especially those on "Wireless."
    I also wish to state that I should like very much an article describing the construction of a closed core transformer for "wireless" transmission to work on alternating currents 110 volts, 60 cycles; and I would suggest that it be designed so that the cost of materials would not be much over $10. An article describing construction of chemical rectifiers for 110 volts alternating current, which would suitably rectify the current for experimental purposes, would be one many readers would be glad to see.

    HAVE a good sending station, having talked with De Forest station, about four miles away. Height of aerial to pole from spark-gap, about 25 feet, and the pole is 35 feet high, with umbrella aerial radiating from top of pole (eight ribs of 7-22 copper wire), each rib about 30 feet long, or total length of, say, 90 feet. Induction coil will give a 7½ inch spark. I use six glass plates, 10 X 12, with tin foil 7 X 9 inches on each side, connected in multiple, for my sending condenser, as shown by illustration. Battery, nine storage cells, worked at about 7 or 8 amperes. Have experimented quite a lot with independent interrupters, and I have now got one that will interrupt properly at a fast rate, and under current as above, without the points welding.
    I have received Bridgeport, Conn., quite clearly. I may have received vessels farther off, but Bridgeport and Wilson's Point, Conn., seem about as far as I have received from inland stations. Fire Island I get very plainly.

    AS a reader of the ELECTRICIAN AND MECHANIC, I would say, in response to the editor's request for suggestions, that I should think an article on the hot-wire ammeter would be of interest. I have tried in vain to find out how this instrument is made and how it works. Even if the construction is too hard or expensive for the amateur, I think an explanation would be gladly received.

    I AM heartily in sympathy with any one that has the "wireless microbe," because I know how it has left me. I cannot get magazines or other articles that treat on this subject fast enough. They are not issued often enough. Wireless telegraphy is my hobby. I would suggest that you give a large portion of the magazine to that subject, especially the construction of practical wireless apparatus. I will ask that you publish an article on the construction and operation of high frequency transformers, as this seems to be one of the new and popular pieces of apparatus.

    I WOULD like to have the names and addresses of members in this city. If the other members would like, we could meet at my office and talk over the matter of forming a local branch. I am the department manager of a large firm, and could furnish a down-town place to meet, with no expense.
