Annotation
Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. The energy spent in pulling a train over its track may be roughly divided into five elements: work against gravity; work of acceleration; internal resist ance that due to friction within the rolling-stock); external resistances, due to interaction between rolling-stock and track; and air resistance. Of these several items the first two, as such, are pretty definite in character and can be figured in a given case with reasonable precision. The last three are extremely hard to separate and have been the source of many difficulties.
