|Women carrying cassava root (?) in the Democratic Republic of the Congo.|
More recently, I returned again to that book, following trails out from it, as in reading advice on wild-country travel by Francis Galton (1822–1911), a long-time member and officer of Britain's Royal Geographical Society. Its author, David Grann, writes,
During the Society's early years, no member personified the organization's eccentricities or audacious mission more than Sir Francis Galton. A cousin of Charles Darwin's, he had been a child prodigy who, by the age of four, could read and recite Latin. He went on to concoct myriad inventions. They included a ventilating top hat; a machine called a Gumption-Reviver, which periodically wet his head to keep him awake during endless study; underwater goggles; and a rotating-vane steam engine. Suffering from periodic nervous breakdowns––"sprained brain," as he called it––he had a compulsion to measure and count virtually everything. He quantified the sensitivity of animal hearing, using a walking stick that could make an inconspicuous whistle; the efficacy of prayer; the average age of death in each profession (lawyers: 66.51; doctors: 67.04); the exact amount of rope needed to break a criminal's neck while avoiding decapitation; and levels of boredom (at meetings of the Royal Geographical Society he would count the rate of fidgets among each member of the audience).Galton attempted to quantify everything about exploration, from daily dietary needs to the maximum feasible load for a donkey, mule, horse, or camel on different types of terrain.
You may sample his calculations in his book The Art of Travel; Or, Shifts and Contrivances Available in Wild Countries, available as a free download from the inestimable Project Gutenberg.
He also rated women highly as "native bearers" for several reasons, quoting the explorer Samuel Hearne on the matter:
As the [Chipawyan?] chief said . . . "When all the men are heavy laden, they can neither hunt nor travel to any considerable distance; and if they meet with any success in hunting, who is to carry the produce of the labour?" . . . "Women," said he, "were made for labour: one of them can carry or haul as much as two men can do. They also pitch our tents, make and mend our clothing, keep us warm at night; and in fact there is no such thing as travelling any considerable distance, or for any length of time, in this country [northern Canada] without their assistance."
"Women," said he again, "though they do everything are maintained at a trifling expense: for, as they always cook, the very licking of their fingers, in scarce times, is sufficient for their subsistence."That was Galton quoting Hearne, I believe, but the original speaker may have been a man named Matonabbee, who has his own Wikipedia entry. In his own voice, Mr Galton comments further, videlicet:
I believe there are few greater popular errors than the idea we have mainly derived from chivalrous times, that woman is a weakly creature . . . . It always seems to me that a hard-worked woman is better and happier for her work. It is in the nature of women to be fond of carrying weights; you may see them in omnibuses and carriages, always preferring to hold their baskets or their babies on their knees, to setting them down on the seats by their sides.So, gentlemen, if you go afield backpacking with a member of the female sex, let her carry the tent.
