invisible, and I was turning away to go when suddenly I bethought me of
the dry preparation of the head that ought to accompany the skeleton.
Without that, the specimen would be incomplete; and an incomplete
specimen would spoil the series. I reflected awhile. It seemed a pity to
spoil the completeness of the series for the sake of a little trouble. I
had a good-sized bag with me and a quantity of stout brown paper in it
in which the bulbs had been wrapped. Why not?

"In the end, I decided that the series should not be spoilt. I need not
describe the obvious details of the simple procedure. When I came up out
of the chalk-pit a quarter of an hour later, my bag contained the
material for the required preparation of a mummified head.

"I soon struck the familiar footpath and set forth at a brisk pace to
catch the late train from Gravesend. It was a long walk and a pleasant

amusement, of Grayson's gang of footpads. It would be a quaint
situation if I encountered some of them and was robbed of my bag. The
possibilities that the idea opened out were highly diverting and kept me
entertained until I at last reached Gravesend Station and was bundled by
