by that bushmen’s clock, the sun. The signal herewith described can be 
made in yarious ways, and attached to the farmhouse itself, if in a 
sufficiently prominent position, or, if not, a good high post sunk in the 
ground will do. The signal itself can be either a plain piece of board or

arm somewhat similar to a railway signal, or a more elaborate one may be made 
by crossing and riveting three 12-inch hoops of light iron, when an open ball 
is formed, which may be arranged to fall down a central rod. The signal itself 
is actuated by the clock device illustrated in the February number of Queensland 
Agricultural Journal of this year. It is advisable to always have the cord that 
raises the signal taut, as the wind is then prevented from entangling the line. 
A glance at the ball or signal-arm from the field where anyone is working will 
tell at once, “What's o’clock?’’ and, though sound appeals to the senses more 
readily than sight, the above-described appliance is a long way ahead of 
pulling the pig’s tail to call the hands to dinner. 
[Why not combine sound with sight? An old-fashioned nipple-gun 
loaded, the nipple capped—a poundweight of iron fixed to the bottom of the 
ball. On the dropping of the ball the gun is fired. This would prevent loss of 
time whilst tired and hungry men are watching for the fall of the time ball —
