"Proper coffee properly made is one of the many blessings," remarks Steffan. "And it would be wrong to withhold such a blessing from anyone. Except perhaps a tiny vicious gibbon," he adds, memories of yesterday still fresh.
What he does next might surprise some who have so far only seen his light-hearted side, or his impractical monkey-drawing side, or his tadpole soup-suggesting side, but is not so surprising to someone who has connected the monkey-drawing to his love of science, of ascribing order, or to, indeed, his reason for being here. Apart from the fame and the stories, of course.
"No more bloody monkey caricatures today, eh?"
Find a small rock that can be tied to the end of my rope. As we go, make soundings of the river to see how deep it is. Record this! Note any depths next to possible landmarks, bends in the river, that kind of thing.
Also - to the other end of the rope, attach a stick, and then knot the rope at 1foot intervals. Every time we stop, let out the rope into the current, count 20 seconds, and take a rough reading of the speed of the current. Note this, in reference to any possible landmarks such as bends also.
Stupid of me to have forgotten an accurate means of telling the time, but seconds at least can be counted by the use of the well known mariners' song Up The Swarthy Eejit, whose verses are exactly 20 seconds long when sung at the right (and obvious) speed.
Try to estimate the distance travelled (I think I alluded to this in RP thread on the first day)
Set off in the boat! No more sketching the hostile wildlife: instead take the above notes, estimates of the width of the river, that kind of thing. Time to be serious!
