deed. The form of words used by the parties indicates that their yo.
intention was that the whole mortgage transaction, as comprised in. = - - :
the deed, should pass, including the surety's covenants as well as
the mortgagor's covenants. Sureties are parties to the mortgage
deed; the word "mortgage" covers the whole transaction to
which the mortgagor and sureties are parties (Coote on Mortgages,
9th ed. (1927), vol. 1, p. 103; Robbins' Law of Mortgages (1897),
vol. 1, p. 78). Sureties' covenants form part of the mortgage
(Bythewood's Conveyancing, 3rd ed. (1840), vol. 6, p. 84; Encyclo-
pedia of Forms and Precedents (1905), vol. 8, pp. 585, 600, 741).
'The only essentials of a mortgage are the charge or conveyance of
land and the simple mortgage debt (Halsbury's Laws of England,
Ist ed., vol. 21, p. 70; see also p. 90, par. 166). The mortgage of
itself implies a debt (King v. King and Ennis (1) ; Coote on Mortgages,
9th ed. (1927), vol. 1, pp. 10, 139 ; Fisher's Law of Mortgage, 6th ed.
(1910), p. 7). The surrounding circumstances support the view that
by indorsing the assignment on the document as a whole the parties
intended it to refer to the whole document. There is no difference in
principle between a surety's covenants and a mortgagor's covenants ;
a mortgagor's covenants, e.g., to pay, and the mortgage, are not
separate deeds. It was so held in Howatson v. Webb (2) and the
obiter dictum upon this point in Bagot v. Chapman (3) was doubted.
'An examination of the issues before the court and the judgments
in Perpetual Executors and Trustees Association of Australia Ltd.
vy. Hosken (4) shows that that case is not an authority to the contrary.
The effect of sec. 91 (4) of the Conveyancing Act 1919 is that it
enlarges the meaning of the words " interest in the mortgage." It does
not cut down the ordinary meaning of the words but merely provides
that they shall have some additional operation (Craies' Statute Law,
3rd ed. (1923), p. 191). The provisions of sec. 91 (2) are permissive,
not mandatory. The parties did not intend that the indorsement
