Sucker

Definition and stakes

Joseph C. Martindale,  First Lessons in Natural Philosophy for Beginners

“ As the fruit cools, the steam is condensed to water, and a vacuum is produced, so that the fruit is kept from the air.
What is the plaything which boys call a sucker?
A sucker is a round piece of leather, with a string fastened to its centre.
How is the sucker used?
The leather is made very soft and wet, so that when pressed against a stone or brick, all the air under the leather is forced out; and when the leather is lifted up, the stone or brick is lifted with it, as is represented by Fig.

“ Perhaps this kindlier bite gives her greater facility in working her pump. The humours, if stagnant, in a corpse, would not respond so readily to the action of the sucker; they are more easily extracted from a live body, in which they move about. ”

Portrait of Philip Henry Gosse Philip Henry Gosse,  A Year at the Shore

“ Is it alive? It hangs helpless and motionless, a mere velvet string across the hand. Ask the neighbouring Annelids and the fry of the rock fishes, or put it into a vase at home, and see. It lies motionless, trailing itself among the gravel; you cannot tell where it begins or ends; it may be a strip of dead sea-weed, Himanthalia lorea, perhaps, or Chorda filum; or even a tarred string. So thinks the little fish who plays over and over it, till he touches at last what is too surely a head. In an instant a bell-shaped sucker mouth has fastened to its side. ”
