The source document uses the word capitol both for capitol and for capital; this usage has been retained. Inconsistent spelling and grammar have not been standardised.

Changes made

Some obvious minor typographical and punctuation errors have been corrected silently.

The text in a dotted box underneath Figs. 10 and 11 has been transcribed from the illustration, not from the actual text.

Page 70: George Washington (vessel’s name) has been changed to George Washington (cf. American Farmer).
