“One [method] is by a Watch to keep time exactly. But, by reason of the motion of the Ship, the Variation of Heat and Cold, Wet and Dry, and the Difference of Gravity in different Latitudes, such a watch hath not yet been made.”

“But old Death, who can't forget,
Waits his time and watches yet,
Waits and watches by the door.”
"The Cottage".
Fairies and Fusiliers (1917)
Context: Through the window I can see
Rooks above the cherry-tree,
Sparrows in the violet bed,
Bramble-bush and bumble-bee,
And old red bracken smoulders still
Among boulders on the hill,
Far too bright to seem quite dead.
But old Death, who can't forget,
Waits his time and watches yet,
Waits and watches by the door.

Before the sun hath thoroughly heat the clime.”
