The old castle at Scarborough was built in 1166 and has a long record of war. Like a great sentinel it watches over the little port in a never ending vigil. It has been considered a strong fortification in its time.

TO PREVENT SATCHEL THEFTS
A RECENTLY patented thief-proof

satchel is to protect the bank mes-
senger against robbery and assault, while
he is carrying money for the firm. A
mechanism guards against its being
snatched from the employe with-
out a great dis-
turbance being at
once raised. This
mechanism com-
prises two alarm.
compartments con-
nected to a small
door in the hollow
handle by means of
cords. If the
satchel is held so as
to maintain the

small door under the handle in open position, the device remains inoperative; but should the hand be removed, the

door will quickly be drawn closed by aspring, the cords attached thereto released, and the alarms instantly sounded.

In one compartment this is accomplished by the connection made with the electric bell, while in the other, a drum, actuated by a spring, is allowed to revolve. The revolver trigger discharges until the spring is unwound, the action being like a rapid-firer.

When the messenger's hand leaves the handle the bell
rings and the alarm gun is fired.
