The Legislature at their session on the 12th of April, 1848, amended the 4th section of the act of April 21, 1846, authorizing the Supervisors to create a loan, and provide further accommodations for the confinement of prisoners, so as to read as follows:—

Sec. 4. The Board of Supervisors of said county, if land should be purchased, are authorized to remove as many prisoners sentenced to hard labor in the County Jail, as they may deem necessary, to the lands so purchased; to place them under such keeper or keepers as they may appoint for that purpose, and to employ them in erecting said penitentiary and workhouse, or such other labor as may be deemed expedient; and they may also authorize and direct the superintendents of the poor of said county to take charge of the establishment (subject to the directions of said Board), and provide the necessary food and clothing for said prisoners, and for those committed as herein next provided. And it shall be lawful for the several magistrates and justices of the peace in said county to commit all offenders convicted before them of petty causes, offenses or misdemeanors, who are in their judgment proper subjects for the penitentiary and workhouse in their discretion.

The city court of Brooklyn was established by an act of the Legislature, March 24, 1849. It had but one judge until 1870, when it was reorganized with three.

On the 10th of March, 1849, an act was passed authorizing the Mayor and Common Council to create a loan, in addition to the loans which had already been authorized by law, not exceeding $50,000, to complete and finish the City Hall.

By virtue of the laws of 1850, chapter 23, the Mayor, Aldermen, and Commonalty were authorized to create an additional loan of $15,000, for the purpose of completing the City Hall of Brooklyn, paying for the fences, ornamenting the grounds belonging thereto, and all other necessary expenses for the full completion and protection of the same.

The subject of building a new court house was again agitated in 1852. On the 17th of September in that year a special committee was appointed by the Board of Supervisors to consider the matter. On the 18th of January, 1853, they reported in favor of applying to the Legislature to carry out the work.

On the 29th of June, 1846, Charles G. Taylor offered a resolution in the Board of Supervisors declaring that it was expedient to purchase lands for the purpose of erecting a workhouse and penitentiary thereon, in accordance with the act of the Legislature passed April 21, 1846. Charles G. Taylor, Barnet Johnson, and James Debevoise, the committee having the matter in charge, reported that 18 acres could be purchased at $200 per acre, and 29 acres for $180 per acre. On the 4th of August, 1846, a resolution was adopted that the same should be purchased, if the titles proved good. On the 4th of December, 1846, Seth Low, John Skillman, and Tunis G. Bergen were appointed a committee to present plans and details.

In April, 1846, the county treasurer issued $2000 of bonds for the erection of the Penitentiary. In 1849 $10,000 more were issued. The total amount of bonds issued up to March 2, 1854, was $155,000. On the 5th of June, 1855, the committee reported that the cost thus far of the easterly and main wing was $111,433.49.

The new Penitentiary was occupied as early as January, 1854, although it was not completed until August, 1856. The total amount of bonds issued for the Penitentiary was $205,000.

It was not until May 3, 1855, that steps were taken to build the female wing of the new Penitentiary.
