sion that inhuman abuse and negli- 

 gence which result in disability or 

 death are not in accordance with 

 sound business methods and common 

 sense. 



The mules represent an average 

 expenditure of about one hundred 

 and fifty dollars each. Consideration 

 for their comfort and health is simply 

 a conservation of capital, according 

 to the more modern viewpoint. An 

 employee who is caught abusing or 

 maltreating one of the animals of a 

 certain western mine, for instance, is 

 instantly dismissed on the theory 

 that if he does it once he will very 

 probably do it again and again.

A Carload Featherbed of 

 Scrap Tin 



THE two men in the picture are not 

 reposing on a carload of hay, or ex- 

 celsior or shavings. They are taking a noon 

 day siesta on scrap-tin loaded at one of the 

 big sardine-canning factories at Eastport, 

 Maine. Tin cans are not composed entirely 

 of tin; they are cut from giant slabs of 

 sheet steel covered with tin. After the 

 cans have been cut from the metal the scrap 

 is loaded into cars and delivered to a de- 

 tinning factory where the tin is chemically 

 removed from the sheet steel. The de- 

 tinned scrap is sent to the steel mill where 

 it is melted into steel billets. 



Getting the Most Out of the 

 Mining Mules 



THE reputation of the mule is un- 

 enviable, to say the least, and to the 

 unthinking there is no better way to 

 make him work than by the unstinted 

 use of the bale stick. In 

 the mines, especially, where 

 mules are used exclusively, 

 humane methods of treat- 

 ment are generally considered 

 impracticable. The little ani- 

 mals are usually at the mercy 

 of brutal and ignorant drivers 

 and are often forced to work 

 from morning until night 

 without food or drink during 

 the day. 



But scientific thought is 

 reaching even the mining 

 mule, and progressive firms 

 are arriving at the conclu- 



Bungalow Fire Stations Are Popular 

 in Residential Sections 



IN residential sections the old type fire 

 station is a blot on the landscape and a 

 cause of annoyance to home-owners, to 

 say_nothing of the scant comfort it affords 

 the' firemen. Modern progressive cities 

 are favoring buildings which conform with 

 the character of the neighborhood where 

 the fire station is located. In business 

 sections brick and stone are used, and the 

 buildings are as nearly like the average 

 type of the locality as possible. In the 

 residential districts the bungalow type is 

 favored. 



The illustration shows a station of this 

 style in Portland, Ore., which might easily 

 be mistaken for a picturesque residence 

 if it were not for the inconspicuous sign 

 above the entrance. The' firemen do their 

 own housekeeping, and there are no cur- 

 tains in the neighborhood more immacu- 

 late, no windowpanes more glistening or 

 grounds more neatly kept.
