On 28th June eighty male convicts from the hulks at Woolwich were received on board, all in good health. They were all put in double leg irons and formed into messes of six men each. The owners of the vessel came on board on 1st July and paid wages in advance to the crew. The weather was very stormy this day and the prisoners were not permitted to go on deck.
The ship dropped down to Norfleet on 2 July and on the 3 July at 11am they got under weigh for the Nore where they anchored at 5.30pm. They received here 50 prisoners from the Retribution hulk at Sheerness. These men received slops and were berthed and divided into messes of six men. On the 4th July 50 prisoners were received from the Bellerophon at Sheerness.
The Larkins weighed anchor at 6am on 5 July and anchored off the South Foreland at 2pm. At 6pm they weighed anchor and continued working round towards Portsmouth to load the remainder of the prisoners.
On 11 July, 40 prisoners from the Captivity and 30 from the Laurel hulks at Portsmouth were received on board. This day also convict George Millington received 3 dozen lashes for abuse to the Sentinel. 
Also boarding at Portsmouth were passengers James Richard Styles, Frederick Dixon, William Francis Weston, Betty (Elizabeth) Weston, and son John Weston. A pilot was received on board on 10th July and they came to anchor at the Motherbank at 11pm that night.
There was a total of 367 men women and children when the Larkins set sail for St. Helen's on 24 July. There had been one more - George Keen, however he was unable to be found and it was conjectured that he had got his irons off his legs, concealed himself among the boats or booms when the prisoners were sent below and took an opportunity to swim to the Isle of Wright, a distance of about two miles.
A great number of prisoners, guards and passengers were very sick for the next 12 hours before they came to anchor off Brixham. William McDonald attended to cleanliness by employing a method of heating sand in the oven and scattering it over the deck. At the next cleaning, the grease and filth was found to be easily able to be swept away. 
The Larkins arrived in Port Jackson on 22 November 1817. On arrival several prisoners made an official complaint of ill treatment and that boxes they had brought on board with them had been plundered. George Handley maintained that he handed over his belongings to the Chief Mate Mr. Laurens and the items had not been returned. An enquiry was held and it was found that the boxes had been stowed below for safe keeping and had been broken open by other prisoners. No further action resulted from the enquiry.
The prisoners were distributed to Windsor, Liverpool and Bringelly.
DEPARTURE FROM PORT JACKSON
Governor Macquarie recorded the departure of the Larkins in his diary......
Tuesday 6. Jany. 1818 ! This morning Sailed from Sydney Cove for Bengal – and ultimately for England – the Ship Larkins Commanded by Capt. Wilkinson; Doctr. Mc.Donald having proceeded as a Passenger on board her.

NOTES AND LINKS:
1). In Sydney in July 1818 eleven desperate convicts made a bid for freedom by attempting to steal two boats. They attempted this while Governor Macquarie was on a tour of Newcastle settlement . Among their number were three men who had arrived on the Larkins - John Giddings, Thomas Scott and James Pocock. Find out more about their attempted escape here. The Governor considered them all to be of the most depraved characters in the colony and after capture they were sentenced to work at hard labour in double irons at the Lime Kilns near Newcastle for up to three years.
2). In 1825 another escape was attempted at Newcastle. This time the convicts were never found. James Johnston who arrived on the Larkins was one of eleven pirates who seized the cutter Eclipse and made for the open sea. Find out more about their audacious escape Here
3). John Popjoy arrived as a convict. He later achieved fame when he assisted in rescuing survivors from a mutiny on the brig Cyprus. Select here to find out more
