From title page: A breif Collection of the yerely Assignements of the Kinges [Majesties] Revennewes, Customes, Imposts and other Profittes hereafter pticularly menconed made and colected by the order and direcon of the Lord Highe Threasorer of England according to a Booke contayning an Establishmente in that behalfe made and signed by his highnes.

Projected budget for royal revenues, probably for James I. Left-hand page of each opening details source of each branch of revenue and amount (or estimated amount) of it. Right-hand page includes destinations for each sum and authority for expenditure. Recipients of sums include the Threasurer of Ireland, Master of the Jewell-house; Cofferer; Master of the Great Wardrobe; the Queen's annuity; Garrisons in teh Low Countries; Treasurer of His Majesty's Chamber; Admiralty; His Majesty's 2 daughters; Ambassador Lidgiers; Berwick; Principal Secretary for Intelligence; Garrisons; Ordnance gunpowder; both Sir John Gilbert's and Lord Danvers annuities; London poor; Gentlemen pensioners; Keeper of His Majesty's Privy Purse; liberies; Master of the Post, of the Horse; Steward of the Star Chamber for diet of the Lorders; diet of Assize Judges; and others. The volume demonstrates on the last used page that the King's debt outstripped income by almost £50,000.

Appears to be written in an Elizabethan or Stuart hand. The volume mentions the King and his two daughters as revenue recipients, leading the original Spencer staff member processing the collection to conclude that the volume was probably written while James I's third daughter Mary (1605-1607) was alive.
