13. Letter from Columbia, May 8th, 18531
You have, heard of course heard of the Errickson Caloric Engine, and I suppose you will have an opportunity of seeing it; from the description it [] appears an ingenious contrivance, but I have no doubt great improvements will yet be made upon it….I am fully employed with the business of my responsible and arduous duties, and the . I frequently have to get up in the middle of the night when anything happens to the ditch, summon a force of labourers and repair the damage if possible, before day light, and I am constantly employed in laying out branch ditches, building dams and bridges, fluming across valleys etc., besides a general supervision of the whole line which extends about forty miles in length and some of it over the roughest country and steepest hillsides you ever saw. I have measured the angle of some of the hillsides and found them less than 45 from the perpendicular height below our flume, while the top of the mountain was about a thousand feet above it. These are some of the California hills.
