Full list of words from this list:

  1. solder
    join or fuse with an alloy
    There were welding tools, soldering irons, and electric drills.
  2. thicket
    a dense growth of bushes
    The jeep trails do not cross it, nor even go close to it, for the mountains around it are forbidding, too steep and rocky even for jeeps, and are covered with thorny thickets.
  3. outcropping
    part of a rock formation that juts above surrounding land
    This clearing was on the far side of the valley, beyond it the mountain wall rose again, a steep slope with big outcroppings of stone—granite ledges that thrust six or ten feet out of the earth.
  4. cynical
    believing the worst of human nature and motives
    It wasn’t that he was lazy and didn’t want to work. He was just more cynical than the rest of us; stealing did not bother him.
  5. insulation
    material reducing transmission of sound, heat or electricity
    He found the rats all grouped around the motor. It had been left plugged in, though it was turned off. They must have been gnawing at the insulation for some reason—at least that’s what he thinks.
  6. incinerate
    cause to burn
    “And do you know? They’re going to. I was joking, of course, but the man in charge of the group didn’t take it as a joke at all. He wanted to know where the farm was, how far away, how many acres, what I raised, how many rats I thought there were. He acted really interested. It seems they wanted to examine the dead rats at Henderson’s, but they couldn’t. He’d already sent them to the town dump, and they were incinerated.”
  7. impasse
    a situation in which no progress can be made
    But on the other side of the stone there was an impasse.
  8. scaffold
    a temporary arrangement erected around a building
    Under Arthur’s direction the ladder-like structures became a scaffolding—four small towers standing one near each corner of the block.
  9. taut
    pulled or drawn tight
    From these bars they now hung pulleys wound with strong, thin cord, and at the ends of the cords they fastened hooks, which they slipped into the oval-shaped holes in the block and pulled taut.
  10. athwart
    across, especially at an oblique angle
    Two rats to a roller, they slipped four of these under the cinder block so that they lay athwart the hole, like bars across a window.
  11. hindmost
    located farthest to the rear
    When it moved off the hindmost of the rollers, as it did every few inches, the two rats in the rear would quickly pick that one up and replace it under the front of the block.
  12. inexorable
    impossible to prevent, resist, or stop
    The bush fought back, then yielded angrily, snapping and crackling before the inexorable thrust of steel.
  13. sparse
    not dense or plentiful
    He reached a sparse thicket of saplings almost out of her sight, and there, abruptly, he fell over on his side and lay still.
  14. wield
    handle effectively
    One of the men wielded his shovel for another minute, and then the doctor peered in.
  15. writhe
    move in a twisting or contorted motion
    Behind the plow, in the moist and shining soil, the rudely-upturned red-brown earthworms writhed in a frenzy to rebury themselves; hopping along each furrow a flock of spring robins tried to catch them before they slid from sight.
