Caterpillar tracks are large (modular) tracks used on tanks, construction equipment and certain other off-road vehicles. The tracks help the vehicle to distribute its weight more evenly over the surface than wheels can, keeping it from sinking in areas where wheeled vehicles (of the same weight) would sink. Caterpillar tracks were first implemented by Benjamin Holt, president of the Holt Manufacturing Company, on November 24th, 1904. Following a merger and name change, The Holt Manufacturing Company went on to become the Caterpillar Tractor Company in 1925.
And from the limbs all vigor went,
Upon his staff the gray-beard leant.
Life's waters from a new-born spring;
Twice, from the seeds that ye had strewed.
When chased by fierce barbarian hordes away,
From Orient's altars, now pollution's prey,
The fugitive from yonder eastern shore,
And on Hesperia's plains sprang up once more
Over the spirit fairer Nature shed,
And through the graceful soul with stately tread
Millions of chains were burst asunder then,
And mildly rose the younger race of men,
With noble inward ecstasy,
And in the veil of modesty,
If on the paths of thought, so freely given,
And, by triumphant Paeans onward driven,
If he with grovelling hireling's pay
Or, with the first slave's-place array
Forgive him!--O'er your head to-day
With you the earliest plant Spring had,
With you, the harvest-chaplet glad,
From clay and stone, with silent triumph throws
What in the land of knowledge.html">knowledge the discoverer knows,
The treasures that the thinker has amassed,
Soon as his knowledge, beauty-ripe at last.
Soon as with you he scales a mountain-height,
The smiling valley bursts upon his sight.
The higher, fairer orders that the mind
Or compass with enjoyment unconfined--
To more luxuriant floods of harmony.
The fair members of the world's vast scheme,
He sees the lofty forms then perfecting--
The fairer riddles come from out the night--
