s. When these barbs are engrailed on their inner edges, the device may be termed a ''pheon''. Woodward's ''Treatise on Heraldry: British and Foreign with English and French Glossaries'' (1892), makes the following distinction: "A BROAD ARROW and a PHEON are represented similarly, except that the Pheon has its inner edges jagged, or engrailed." Parker's ''Glossary of Terms Used in Heraldry'' (1894) likewise states, "A broad arrow differs somewhat ... and resembles a pheon, except in the omission of the jagged edge on the inside of the barbs." However, A. C. Fox-Davies, in his ''Complete Guide to Heraldry'' (1909), comments: "This is not a distinction very stringently adhered to."

Use for British Government property

The broad arrow was used in England (and later Britain), apparently from the early 14th century, and more widely from the 16th century, to mark objects purchased from the monarch's money, or to indicate government property. It became particularly associated with the Office or Board of Ordnance, the principal duty of which was to supply guns, ammunition, stores and equipment to the King's Navy.


Origins

The origins of the broad arrow device used by the Board of Ordnance are debated. The symbol is widely supposed to have been derived from the pheon in the arms of the Sidney family, through the influence either of

A newspaper ''THE BROAD ARROW '' described as 'A PAPER FOR THE SERVICES' (and also with the 'Broad Arrow' mark in its header) was published from 1833. It later extended its title to include ''The Naval and Military Gazette''. It was published during WW1 by which time it was printed by WH Smith and son. It later became ''THE ARMY, NAVY AND AIR FORCE GAZETTE : INCORPORATING "THE BROAD ARROW" AND "NAVAL AND MILITARY GAZETTE'' In 1936 ''The Army, Navy and Air Force Gazette'' amalgamated with the ''Naval and Military Record'' to form ''United Services Review''.

, which contained a Mast Preservation Clause specifying, in part: Initially England imported its mast trees from the Baltic states, but it was an expensive, lengthy and politically treacherous proposition. Much of British naval policy at the time revolved around keeping the trade route to the Baltics open. With Baltic timber becoming less appealing to use, the Admiralty's eye turned towards the Colonies. Colonists paid little attention to the Charter's Mast Preservation Clause, and tree harvesting increased with disregard for broad arrow protected trees. However, as Baltic imports decreased, the British timber trade increasingly depended on North American trees, and enforcement of broad arrow policies increased. Persons appointed to the position of Surveyor-General of His Majesty's Woods were responsible for selecting, marking and recording trees as well as policing and enforcing the unlicensed cutting of protected trees. This process was open to abuse, and the British monopoly was very unpopular with colonists. Part of the reason was that many protected trees were on either town-owned or privately owned lands. Colonists could only sell mast trees to the British, but were substantially underpaid for the lumber. Even though it was illegal for the colonists to sell to enemies of the crown, both the French and the Spanish were in the market for mast trees as well and would pay a much better price. Acts of Parliament in 1711, 1722 and 1772 ( Timber for the Navy Act 1772) extended protection finally to trees and resulted in the
