Well, the sentence structure is strongly reminiscent of Longefellow's epic "Song of Hiawatha".

Here is a very brief excerpt

By the shore of Gitche Gumee,

By the shining Big-Sea-Water,

At the doorway of his wigwam,

In the pleasant Summer morning,

Hiawatha stood and waited.

For a time I stood regarding

All the air was full of freshness,

All the earth was bright and joyous,

And before him, through the sunshine,

Westward toward the neighboring forest

Passed in golden swarms the Ahmo,

Passed the bees, the honey-makers,

Burning, singing in the sunshine.

That 6th line was not part of the verse, but doesn't it fit in well?  Every line in the poem has 8 syllables, and as you read each line you want to break about halfway through.

But I suspect the puzzle author is focusing more on the lengths of the words in that phrase

For a time I stood regarding = 3 1 4 1 5 9

Like I always say, give enough monkeys enough typewriters and eventually they will write the first 10,000 digits of PI.
