ART. 57] FRAUD——PEINCE GEORGE'S COUNTY. 1403

The act of 1868, ch. 357, discussed and construed. Whether the plaintiff's
failure to discover his cause of action was due to a failure to exercise due
diligence, or to the defendant's concealment of his wrong, is ordinarily a
question for the Jury. Where fraud is committed by an agent within the
scope of his employment, the bar of the statute is removed as against the
principal. New England Ins. Co. v. Swain, 100 Md. 572.

A plaintiff held not to have used ordinary diligence so as to entitle it to
the benefit of this section. Stieff Co. v. Ullrlch, 110 Md. 634.

Knowledge, or want of diligence on the part of trustees, Imputed to plain-
tiff. Reeder v. Lanahan, 111 Md. 384.

For a discussion of this subject prior to the adoption of this section, see
MacDowell v. Goldsmith, 2 Md. Ch. 390.

As to the extension by fraud of the time within which an appeal may be
entered, see art. 5, sec. 32.

1906, ch. 803.
