I picked up my Aerograph 95 airbrush and got to work.

An aërograph message was sent to King Edward and the President of the United States.

Halliday was studying a aerograph on the wall.

He ran back, switched the electric current off the aerograph machines at the base of the observatory, and turned it on to the searchlight which was on the top of the equatorial dome.

The private telephone and telegraph wires between Whernside House and Settle and the aerograph apparatus at the observatory were working almost incessantly till dawn, sending and receiving messages between this remote moorland district and London and the seat of war, as well as Bolton and Pittsburg.
