NEEDLES.

Illustration: DRILLING THE EYES.

The manufacture of needles is one of those arts in which manual

dexterity is acquired by minute subdivision of labour, each artisan

performing only a small part of the process, but so often, that the

most wonderful rapidity and accuracy are obtained, insomuch that

although each needle has to pass through nearly 150 hands (together

with expensive machinery) before finishing, yet they may be bought

at an astonishingly low price.
