This section referred to in holding that legislative practice reveals tendency to limit,
not extend, Governor's power of removal. Removal of postmasters. Myers v. U. S.,
272 U. S. 249, 71 L. Ed. 221 (dissenting opinion).

Act of 1914, ch. 750, held to have been validly passed. The amendment of a bill by
striking out all after "A Bill," upheld. When a bill is properly authenticated it cannot
be impeached by the Journals alone or by oral testimony that the Constitution was not
observed in its passage. There must be clear and competent evidence to rebut the
presumption that a duly authenticated and published act has been validly passed. When
one bill is substituted for another and it appears that the original title was printed on
the back of amended bill, to invalidate the bill it must appear that original title alone
was read. Thrift v. Towers, 127 Md. 55.

with the Federal Constitution, and is valid. Extent of the power of the legislature over
the city of Baltimore. The title of the act of 1910, ch. 180, is sufficient under art. 3,
sec. 29, of the Constitution. Thrift v. Laird, 125 Md. 57. (This decision was based on
the law as it stood prior to the act of 1914.)
