pile ready on the keep, and a watch always stationed there. He is to light
it at once when he sees smoke or fire from either of the three points. Let
the men at the outposts be relieved every four hours. They must, of
course, be mounted. Let one of the two remain by the faggots, and let the
other ride three or four miles in advance, and so post himself as to see a
long distance down the road.

"If he sees a force advancing he must gallop back at full speed to his
comrade, and light the fire. Have a gun always loaded on the keep, and
have a brazier burning hard by, with an iron in it, so that the piece may
be fired the instant smoke is seen. It might be two or three minutes
before the beacon would give out smoke enough to be noticed, and every
minute may be of the greatest importance to the vassals. As soon as you
return from setting the posts see that everything is in readiness here. I

marshes. They need not trouble to hunt them all up today. Let them bring
the principal herd, the others we will fetch in to-morrow, or let them
range where they are until we have further news."

In a few minutes the castle resounded with the din of preparations under
the superintendence of Sir Eustace. The men-at-arms and archers carried up
stones from the great pile that had been collected in the court-yard in
readiness, to the various points on the walls that would be most exposed
to assault. Others were employed in fixing barricades in the court-yard at
the rear for the reception of the herd of half-wild cattle. The water was
turned from the little rivulet running down to the Somme into the moat.
Two or three bullocks were killed to furnish food for the fugitives who
