In-Doors and Out-Of-Doors

There are three gifts apart, whereby good men
Do good unto their fellows. Some can press
Power out of heartless books with subtle pen,
Through steadfast years of in-doors weariness.
Others there are, who in the outward fret
Of states and towns with their best wealth at war,
With help from heaven, have kept the world as yet
From working towards its doom too fast or far.
And there are some whose lives are out-of-doors,
In hopeful spots the Cross and Keys applying,
Unfastening there from Earth's green shining floors
The ponderous curse that hath so long been lying
O'er its hushed fields, bewildering heathen guess
With intricate, unmeaning loveliness.
