1. In 1784, New Hampshire became the ninth state to ratify the United States Constitution, which had been signed in Philadelphia the previous year. This helped to make the Constitution the supreme law of the land and paved the way for the growth of the federal government.

2. In 1805, the New Hampshire Patriot newspaper reported on the death of Dr. Samuel Tenney, a prominent physician and politician. Tenney had represented New Hampshire in the Continental Congress and had served as a state senator and judge. He was also a respected physician who had studied medicine in Europe.

3. In 1845, the New Hampshire legislature authorized the construction of a state prison in Concord. The prison, which is still in use today, was intended to replace the old Hillsborough County Gaol in Manchester, which had become overcrowded and unsanitary.

4. In 1872, the New Hampshire legislature passed a law making it illegal to hunt deer with dogs. This was seen as a progressive move at the time, as many other states allowed hunting with dogs. The law was aimed at preventing the indiscriminate killing of deer and protecting the state's wildlife.

5. In 1956, New Hampshire officially adopted the white-tailed deer as its state animal. The deer had been hunted in the state since colonial times and was an important source of food for early settlers. Today, the deer is a beloved symbol of the state's natural beauty and is often seen in fields and forests throughout New Hampshire.
