But e’en the generous spirits of the brave,

Subdued by toil, a friendly respite crave;

They, with severe fatigue alone opprest,

Would fain indulge an interval of rest.

Far other cares the Master’s mind employ,

Approaching perils all his hopes destroy:

In vain he spreads the graduated chart,

And bounds the distance by the rules of art;

Across the geometric plane expands

The compasses to circumjacent lands;
