King’s Journal: Charles Mac Lennand a boy of 14 yrs old was discovered stealing Rum out of the Surgeons Tent, punished him with 3 Dozn lashes. I have great reason to suppose some others were concerned with him, but not having sufficient proof against them, I forbear taking any notice of it, being determined & having assured the people that the next person which I detected in any theft whatever would be made a severe & dreadful example of.
King in Hunter: 20th, a convict boy was detected stealing the surgeon’s allowance of rum, out of his tent. This boy was only fifteen years old, and was transported for seven years. I ordered him to be punished with an hundred lashes, which I hoped would have a good effect.
