Holograph notes on rate of output of copper

<332r>

Ten mills working 20 hours per day sufficed for coyning 90000^li per week in shillings, or 15000^li per day, or 150000 shillings in 10 hours & one mill for 15000 in 10 hours. And 15000 half pence is 375^lwt at 20 pence per pound weight. And this is done with 5 horses & a miller at 3^s per day each & 2^s a labourer, that is for 20^s, or 240 pence, that is for $\frac{16}{25}$^d per pound weight, or 2^d per 3^lwt. And if the copper go but twice through the mill, it will be done for $\frac{4}{9}$^d per pound weight.

One cutter dispatches 26 pieces in a minute that is 780 pence in an hour that is 40^lwt in an hour or 320^lwt in 8 hours. And this is done with a moneyer & a labourer to bend the scissel &c for 7^s that is for $\frac{1}{4}$^d per pound weight.

One flatter with two men dispatches 1$\frac{1}{2}$^lwt in a minute, 90^lwt in an hour & 720^lwt in 8 hours for 4^s, or 1^lwt for $\frac{1}{15}$^d.

One Marking Engin dispatches 200^lwt per diem for 3^s & 14^d per diem Smiths works, & works for $\frac{1}{4}$ per pound weight.

One press dispatches 40^lwt in an hour & 320^lwt in 8 hours for 13^s, & so works for $\frac{1}{2}$^d per pound weight.
