10 days 15 hours and 13 minutes. This achievement may be more fully
appreciated by comparing it with the transcontinental relay race in
which a courier carried a message from President Taft to President
Chilberg, of the Alaska-Yukon-Pacific Exposition, in September-October,
1909, in 10 days 5 hours, by using thirty-two cars and as many
different drivers who knew the roads over which they ran.

Those who are fortunate enough to have friends who own cars know that
automobiles can climb hills; and that the accepted way to do it is to
throw in the extra special high gear, tear the throttle out by the
roots, advance the spark twenty minutes, and push hard on the steering
wheel. The fact that the car will overlook such treatment and go ahead
is a source of never-failing wonder. Indeed, when it comes to
hill-climbing the automobile is so far ahead of the locomotive that it
seems like wanton cruelty to drag the latter into the discussion at
all.

The steepest grade on a railroad doing a miscellaneous transportation
business climbed by a locomotive relying on adhesion only is on the
Leopoldina system in Brazil between Bocca do Monte and Theodoso, where
there is a stretch of 8-1/3 per cent. grade with curves of 130 feet
radius. There are some logging roads in the United States with grades
of 16 per cent. How trifling this seems when compared with the feat of
a Thomas car which climbed Fillmore Street, San Francisco, which is
alleged to have a gradient of 34 per cent., with twenty-three persons
on board. As 25 per cent. is regarded as the maximum safe gradient for
an Abt rack railway, since the cog-wheel is liable to climb out of the
rack on any steeper grade, it will be seen that the strain upon the
credulity of the hearer of this story is almost as great as that upon
the car must have been.
