Selling by Show-Window Telephone 



THE drawback to window demon- 

 stration of any character is the in- 

 ability of the demonstrator to get his 

 "message across.'' He can clearly point 

 out the talking points of the article under 

 demonstration, but he can talk about it 

 through the medium of lettered cards 

 only. It is obvious that this method is 

 very unsatisfactory. To overcome the 

 objection and bring the demonstrator 

 nearer his audience, an electric company 

 has developed a loud speaking telephone 

 equipment. 



The equipment consists of a special 

 transmitter and a pair of loud speaking 

 receivers and horns. The operation of 

 the system is simple. The demonstra- 

 tor connects the horns and receivers oh 

 both sides of his window, just high 

 enough to be outside the reach of mis- 

 chievous youngsters. The transmitter 

 is placed inside the window and is wired

with the battery of six dry cells in 

 series. 



As the demonstrator wishes to bring 

 out each point, he simply speaks into 

 the transmitter and his voice is magni- 

 fied by the receivers and horns and car- 

 ried to the audience outside. The equip- 

 ment not only brings the demonstrator 

 and his audience into more intimate con- 

 tact, but serves as an auxiliary attrac- 

 tion to the display itself. It has proven 

 a success wherever used. 



Oil is Cheaper than Coal 



TWO large steamships, the Finland 

 and the Kroonland, will be changed 

 from coal to oil burners. By this, 

 change it is expected that $9,000 will 

 be saved on fuel and $3,500 in wages 

 on each trip. In addition, by the large 

 space now occupied, coal may be used 

 for the storage of freight. A total sav- 

 ing of $37,500 is expected on each trip. 



The window salesman need no longer resort to cards and dumb-show. By means 

 of a loud-speaking telephone he talks to his audience on the sidewalk
