And o’er the figured plane attentive bends;
To him the motion of each orb was known,
That wheels around the sun’s refulgent throne;
But here, alas! his science nought avails,
Skill droops unequal, and experience fails;
The different traverses, since twilight made,
He on the hydrographic circle laid;
Then, in the graduated arch contained,
The angle of lee-way, seven points, remained.—
Her place discovered by the rules of art,
