These evil results may always be minimized by placing a piece of millboard between the culprit and his victim.

I have seen lovely bindings sadly marked by such uncanny neighbours.
When your books are being "dusted," don't impute too much common sense to your assistants; take their ignorance for granted, and tell them at once never to lift any book by one of its covers; that treatment is sure to strain the back, and ten to one the weight will be at the same time miscalculated, and the volume will fall.

Your female "help," too, dearly loves a good tall pile to work at and, as a rule, her notions of the centre of gravity are not accurate, leading often to a general downfall, and the damage of many a corner.

Again, if not supervised and instructed, she is very apt to rub the dust into, instead of off, the edges.

Each volume should be held tightly, so as to prevent the leaves from gaping, and then wiped from the back to the fore-edge.
