Coal and the Miner-Rambles Among our Industries by William J Claxton. 
There was a wise custom of the old trade guilds, the
"wander-year", when the apprentice, having served his time, spent a year in wandering from one master to another before settling to his trade.
The aim of the
wander-year was to broaden the knowledge of the young tradesman and teach him the dignity of his craft. A like purpose has led the publishers to add to their
"Rambler" Series a number of books dealing with the main industries of the country. It is well that boys and girls, before passing out into the busy life of the world, should learn something of the reality and something of the romance of the great industries by which that life is sustained.
