"parents'' of the "twins." They have 

 been lead by the pocket-book into de- 

 lineating a metropolitan wealth, super- 

 abundant delightful wealth, and calling 

 it the country and the suburbs. They 

 boldly and confessedly are "class" mag- 

 azines and in that class they are good. 

 But they have wideiy diverged from the 

 connotation of their names and in draw- 

 ing away from their true sphere, as sug- 

 gested by those names, they have left a 

 space that is broad and deep. "The 

 Guide to Nature" ?* coming to fill that 

 vacancy. It will tell you truly of coun- 

 try life as well as of the delights of the 

 suburbs. It will try to show you what 

 to look for and to look at in the country, 

 and what to take to your home in the 

 city or in the suburbs. It will not deal 

 entirely nor frequently in "glittering 



generalities," although it hopes to spar- 

 kle sometimes, and at all times to grow 

 steadily with the fire of nature's inspira- 

 tion, fanned by the breezes that swing 

 above the fields and toss the clouds 

 across the sun. The sight of a leaf 

 lying on a cluster of bluets in a 

 grassy meadow will be more welcome, 

 and will more thoroughly merit a full 

 page illustration, than will a thousand 

 Fur rugs of a roomful of priceless tap- 

 estries. It will be a guide to nature, not 

 a sign-post to point out the useless things 

 that unlimited wealth can buy. A de- 

 scription and picture of an invisible ob- 

 ject as it appears under the microscope 

 will give "The Guide" greater satisfac- 

 tion than the portraits of forty bulls of 

 Bashan.

HEAVIEST LOCOMOTIVE IN THE WORLD 



All records in locomotive construction 

 have been broken by the completion at 

 the Schenectady Works of the American 

 Locomotive Company one of the three 

 Mallet Articulated Compounds for the 

 Erie Railroad. It was only three yCars 

 ago that the railroad world was astound- 

 ed by the enormous size of the first re- 

 presentative of this type in America, the 

 articulated compound built by the same 

 company for the Baltimore & Ohio Rail- 

 road. These Erie engines, however, sur- 

 pass their predecessors as much as that 

 engine did its contemporaries, and they 

 stand in a class by themselves as the 

 largest and most powerful locomotives 

 of this or any other type in the world. 



The articulated compound locomotive 

 was first introduced in this country to 

 solve the difficulties brought about, on 

 roads with long and steep grades, by the 

 rapid increase in size and power of the 

 modern road engine. On such grades 

 several helpers are required to handle a 

 train which a single road engine can

bring to the hill, or else the train must 

 be "cut." This entails trouble and de- 

 lay in the moving of traffic. To solve the 

 problem it was suggested to concentrate 

 the helping power in one combined set of 

 engines flexibly connected under one 

 boiler. In this way the power of each of 

 the ordinary engines could be put in the 

 hands of a single crew. 



This method was brought into reali- 

 zation on the Baltimore & Ohio Railroad 

 in the locomotive above referred to, and 

 the decided success of this engine during 

 the time it has been in service has 

 brought about the increasing popularity 

 of this type, which has reached its high- 

 est development in the engines just de- 

 livered to the Erie Railroad. 



Each of these enormous locomotives 

 is in reality two engines combined in one. 

 The rear engines are carried in frames 

 which are rigidly attached to the boiler ; 

 while the forward engines are carried in 

 frames which are not rigidly attached 

 to the boiler, and are in fact a truck 

 which swivels around a centre pin locat-
