The next letter informs Bartram that his collection of seeds of 
forest trees had brought £18 13s. 3d. from Lord Petre, who also 
promised an annual subscription of ten guineas to aid him in 
making further discoveries. 
“Lord Petre is very willing to contribute very handsomely towards 
it. He will be ten guineas, and we gre in hopes to raise ten more 
This we think, will enable thee to s apart a month, two, or three, to 
make an excursion on the banks of the Schaylkill, to trace it to its 
fountain. But so great an undertaking may require two or three years, 
and as many journeys, to effect it, so we must leave that wholly to

should fit see what they have for their money. This | can assur

expectations,” —p. 75. 
An excursion to Maryland and Virginia being planned for the 
succeeding autumn, Collinson sends him particular instructions, 
and letters of introduction, “which letters come to J. Logan to 
Save thee postage,” commending him to his friends in those parts, 
to Robert ‘Gober Col. Custis, Col. Boyd, Isham Randolph, &c.
