[From Atholl Papers - AP 42B-24]

Sketch of an estimate of the value of the Isle of Man [by John (3) Duke of Atholl]

(this appears to be an early draft dating from 1764 - a fuller and later version also exists)

The revenues of the Isle of Man for 9 years from 1754 to 1762 both inclusive amount to £65040 15 2 which at a medium of years is £7226 15 0½ per annum, this is chagreable with a quitt rent payable to Sr M Lamb of 101 15 11 which being deducted there remains 7124 19 1½ (The years 1763 & 1764 will be much the same as the others but are not sett down, as an exact account of them has not yet been received)

Nothing is deducted from the above sum for Officers salleries, as the having those offices in his gift is an advantage to the Lord of the Isle by enabling him to make handsom provision for sundry friends whose perquisites are much more considerable than their salleries - As the revenue of the Isle of Man is subject to no taxes or deductions whatever it is hoped that 35 five years purchase will be thought as reasonable demand which will amount to 249373-9-4½

The Lord of the Isle of Man has in his gift of eclesiestical preferements

which at 10 years purchase will amount to 8400

The Lord of the Isle of Man is a loyal fief of England and consequently the Lord of the Isle has the whole regal power vested in his person, to make laws coyns money has the power of life & death and does all other acts of soveraingty [sic] that any other free state can do. by his letters patent from the Crown of England he has not only the soveraignty by land but is also Lord Admiral of the seas round the Isle, there can be no rule of valuation for this unless it be the Scotch jurisdictions, the Duke of Argylls which was all respects much inferior to this was valued at £21000 so this may be esitmated at duble 42000
there is besides this Castles House and gardens cannon fire arms &c not valued in the above

249373 9 1½
8400 0 0
42000 0 0
299773 9 4½

For the power of judging what duties the Lord of the Isle thinks fitt --
