The same Act _empowers one Justice to grant a warrant to search in the day time for such metals suspected to be stolen, as by the oath of one witness may appear to be deposited or concealed in any house or place_; and if goods are found, the Act goes so far as _to empower two Justices to adjudge the person having the custody of the same, guilty of a misdemeanor, if he cannot produce the party from whom he purchased, or give a satisfactory account how they came into his possession; and the offender shall, for the first offence forfeit 40s. for the second 4l. and for every subsequent offence 6l._ Sec. 2; 6.

This Act also _empowers officers of justice (and watchmen while on duty) to apprehend all persons suspected of conveying any stolen metals, as already described, after sun-set or before sun-rise; and if such persons cannot give a good account of the manner in which they were obtained, two Magistrates are in like manner authorized to adjudge them guilty of a misdemeanor, and they forfeit forty shillings, &c._ Sec. 3; 6.

_The persons also to whom such articles are offered for sale or to be pawned, where there is reasonable ground to suppose they were stolen, are empowered to apprehend and secure the parties and the materials, to be dealt with according to law. And if it shall appear even on the evidence of the thief, corroborated by other testimony, that there was cause to suspect the goods were stolen, and that the person to whom they were offered, did not do his duty in apprehending the person offering the same, he shall be adjudged guilty of a misdemeanor, and forfeit twenty shillings for the first offence: forty shillings for the second, and four pounds for every subsequent offence_, Sec. 5, 6. And so anxious has the Legislature been to suppress the evil of stealing and receiving metals, that the 8th Section _entitles the actual Thief to a pardon, on the discovery and conviction of two or more of the Receivers_. And the 9th Section _screens from prosecution any person stealing such metals, who shall discover the Receiver to whom the same were delivered, so as a conviction may follow_.--In spite, however, of these numerous and apparently effectual checks, it is to be lamented that the evil has continued to increase.
