all the varieties of grain form & colour.
The most convenient size & shape is an oblong of the dimensions of a mans hand & nearly of the same thickness.
Immediately after being broken off, they ought to be protected from the moisture of the hand & envelopd [enveloped] in paper, numberd [numbered] & deposited in a Barrel. The numbers are to be continued until the Barrel is full, when the Barrel too is numberd [numbered] or letterd [lettered].
The numbers on the paperd [papered] specimens refer to a short Catalogue which records the places where the Specimens were found, together with such circumstances immediately connected with them as are thought worthy of being subjoined, but as for any general information on this subject it must be drawn up in a separate form after the Country has been more fully investigated & the dispersed local information acquired in repeated excursions has been collected into a focus.
The Miner who will regularly attend the party upon these occasions must be employd [employed] in breaking the Specimens with his Sledge Hammer & in carrying them in a large leathern pocket appendant like a Gamekeepers bag to his side. It is hoped that he will generally be pretty well loaded.
If the Specimens are well chosen, that is, if they are of the forms above prescribd [prescribed], taken from the more solid parts of the rock, exhibiting a fresh fracture on all sides, unsullied by the touch, every object of their collection will be attained, but if these circumstances from their apparent triviality are not carefully attended to, the labor bestowd [bestowed] on the collection will be of little utility.
