job. Moreover, it was maintained with 

 greater care than most roads wish to 

 bestow on an engine these days. 



One of the most remarkable features 

 of the E-6-S engines is the lightness of 

 their moving parts. This was made pos- 

 sible by the use of a very fine quality of 

 steel. It will be observed that by saving 

 weight in the construction of these parts 

 a larger and heavier boiler could be used 

 without exceeding the limitations as to 

 total weight imposed by the permanent 



not been made for such variations. The 

 Pennsylvania permanent way is strong 

 enough to stand this punishment, and so 

 the new engines roar along in perfect 

 safety. 



The weight of this type, without ten- 

 der, is 240,000 pounds, of which over 

 133,000 is on the drivers. The cylinders 

 are 23^ x 26 inches and the boiler is 

 78^/2 inches in diameter at the first ring. 



Thus far, no attempt has been made 

 to ascertain how fast a locomotive of this

 driving wheels is greater than many roads 

 could stand. It should be understood 

 that the difference between the static and

 of the runners have not tried to investi-

 such engines have been permitted to ex-

 however, that they could attain 90 miles 

 per hour perhaps more. 



FISHNETS PROTECT ROOFS 



The thrifty fishermen who inhabit the 

 coasts of England have discovered a new 

 use for their old fishnets. During the 

 heavy gales which blow in from the 

 Atlantic during the winter season the 

 fishermen are in constant fear of their 



straw-thatched roofs being torn away. 

 To counteract the disastrous effects of 

 the wind old fishnets are thrown over 

 the roofs and their ends made fast to 

 the stout poles which project from the 

 eaves of the houses. As the net dries 

 it shrinks, and the roof is held down 

 securely.
