Started processing these soils at about 1815 today -- rather late for samples taken about 1100, so might be a bit too dry.
Dry weights taken 21 hours later.

tare = c(7.981,7.940,7.945,7.991)
wet = c(74.357,97.473,90.836,98.365)-tare
dry = c(48.354,72.210,67.464,78.623)-tare
moist = 100*(wet-dry)/wet
vol = 3*pi*(5.31/2)^2
rho = dry/vol
