The jolly, on the other hand, is used
for making such things as covers, the top surface of which has already
been moulded. The profile set in the jolly-lever makes the
bottom. That, as I told you, is how we get the base of our plates. For
certain articles the jigger is preferred; for certain others the
jolly; but the aim of both is the same, and the workers at the
machines are all called jiggermen. After an article is taken from the
jigger or jolly it is dried and carried to the turning-lathe to have
its surface smoothed and finished."
"And does it take all these men to run a jigger?" whispered Theo,
pointing to the moving figures that hurried to and fro.
"An organized group of men is employed at each machine," answered
Mr. Marwood. "First there is the _clay-carrier_, who must bring the
material to the workmen; then there is a second man called the
_batter-out_ who takes from the carrier the piece of clay cut into the
proper size, and after laying this on a block gives it a strong blow
with a plaster-of-Paris bat to flatten it for the jiggerman. When
making simple objects such a man can give the article quite a start
even with one stroke. You can see that some such beginning must be
made before the jiggermen can handle the material.
