 ond. Multiply 1087 by the 

 number of seconds during the 

 interval between the flash 

 and the thunder and the re- 

 sult is the distance between 

 you and the storm. As a 

 rule, from twelve to fifteen 

 miles is the greatest distance 

 thunder can be heard.

Moving Furniture with a Motorcycle 



THE wide range of usefulness of the 

 motorcycle is shown in its utiliza- 

 tion for commercial purposes. A furni- 

 ture dealer in Westerley, Rhode Island, 

 has found that he can make deliveries 

 on a side-car as efliciently and more 

 economically than by the horse and 

 wagon heretofore used. 



Upon a side-car chassis, he con- 

 structed a small van which can be ex- 

 tended when needed to a length of eight 

 feet. Side boards are added 

 to this, so that a large load of 

 furniture can be carried. The 

 motorcycle in the photo- 

 graph carries upon its side- 

 car two sofas, one large and 

 one small, one upholstered 

 and one plain rocker and two 

 upholstered straight-back 

 chairs. This load is handled 

 with ease in spite of its bulk 

 and weight. 



Locating a Thunderstorm 



WHEN you see a flash 

 of lightning, count the

 as seeing the lighting the 

 instant it flashes. But sound 



Stores on Wheels 

 DAYTON woman who 

 conducts a tobacco and 

 confectionery shop has insti- 

 tuted a system of traveling 

 stores that has served to in- 

 crease her business to an 

 appreciable extent. The 

 traveling stores are in charge 

 of small boys, but they are so 

 arranged that the business is carried on 

 in a systematic manner. 



Each store is a wagon — a two-wheeled 

 cart to be exact — and the goods are pro- 

 tected from the elements and the dust by 

 glass covers. The carts are, in fact, 

 traveling show-cases, and a full assort- 

 ment of goods is carried at all times. 

 An interesting and business-like feature 

 is the special compartment for a cash 

 register, which makes the outfit com- 

 plete.
