The highway to Pagosa Springs followed the San Juan River up the pass to the top of the Rocky Mountains while side streams, arush with melting snow, ice cold to the touch, cascaded down from the roof of the sky, thousands of feet above.
It had stirred before, but not with the warm tingle melting its icy cage.
The warm wind assisted the sun in melting the snow and most of it was already gone, leaving a trail of sloppy mud to the barn.
In an experiment on 3500 grams of paraffin produced from shale (melting point 44'5° C.) they obtained nearly 4 litres of liquid hydrocarbons, which they subjected to fractional distillation, and on examining the fraction distilling below loo° C., they found it to consist mainly of olefines.
It crystallizes in colourless plates melting at 20°C. and boiling at 202°C.; it is insoluble in water, but readily dissolves in the ordinary organic solvents.
