ENUNCIATOR  TRIED  OUT  AT  ROUND-UP
__________

    As a result of a demonstration of the electric enunciator at Round-up Park this morning it is more than probable that the spectators at the frontier show next month will receive their information about the events and performers through horns affixed to post in each section of the grandstand and in front of each section of the bleachers. The demonstration showed conclusively that the electric enunciator has been perfected to a practical point and the directors of the association were much impressed with its utility. A meeting will be held this afternoon or this evening to discuss terms for the purchase or lease of a sufficient system.
    The demonstration was made by J. C. Scott of the Portland Enunciator Company, assisted by John Vaughan, local electrician. For the purpose three horns about the same size as the average phonograph horn were attached to the section posts of the grandstand and connected with batteries. Lee Drake, official announcer of the Round-up, talked into a receiver in a tone but little louder than the average conversational tone and the announcements were heard clearly and distinctly throughout the Grandstand. The demonstration was made without employing the amplifier which Mr. Scott declares will offset any counter effect which a crowd in the grandstand or other noises will have.
    The cost for installing a system such as would reach every section of the grandstand and bleachers would be close around $1500 and as that is a considerable sum of money, the directors are considering the matter of leasing the equipment this year. Inasmuch as the company is desirous of securing the advertising which the employment of the enunclator will give, no difficulty is anticipated in reaching satisfactory terms.

ENUNCIATOR  SECURED  FOR  THE  ROUND-UP
__________

    Announcements of the events, winners and performers by an electric enunciator will be one of the added features of the Round-up next month, the action of the board of directors last evening in closing a deal with the Oregon Enunciator Co. of Portland assuring this new convenience for the spectators. Pendleton will thus be able to boast the second open-air park in the United States equipped in this manner, the White Sox ball park of Chicago being the first to install the enunciator.
    In order that all sections of the grandstand and bleachers can be reached clearly and distinctly by the transmitted announcements, 45 of the instruments, known as the multa Musola machines, will be installed, 15 in the grandstand and 15 in front of each of the bleacher sections. Each will be provided with an amplifier so that the sound will carry well. The company will send a special man to install the apparatus and to superintend it during the three days. In connection with the enunciator, a phonograph attachment will be supplied and records will be played before the show and during the same.
    The installation of the enunciator is in line with the policy of the association to place the comfort and pleasure of spectators above everything else. It was the same policy which caused the directors to decide against allowing any hawkers or venders inside the park other than those who supply the crowd with programs and soft drinks.

Newsy  Notes  of  Pendleton
Records  for  Enunciator
    Such lulls as there may be at the Round-up will be filled by band music and also by selections on the phonograph attachment to the electric enunciator. The Portland company has sent up a list of the records available and the directors will make their selection from it. The equipment for the enunciator system is being shipped from Chicago and will arrive here soon.

SPORT-NEWS  POT  POURRI

    San Francisco's new ball park is to be equipped with multa musola phonographic instruments. This contraption is a cross between a phonograph, an auto horn and a ballyho guy. Batteries and changes are announced to the grandstand and bleachers and children driven into spasms. Ewing's new park, too, is within hailing distance of the cemetery. Finish the paragraph yourself.
