I was reading Emerson: The Mind on Fire and came across this passage:
Coleridge notes that there are four kinds of readers: the hourglass, the sponge, the jelly bag, and the Golconda. In the first everything that runs in runs right out again. The sponge gives out all it took in, only a little dirtier. The jelly bag keeps only the refuse. The Golconda runs everything through a sieve and keeps only the diamonds. Emerson was not a systematic reader, but he had a genius for skimming and a comprehensive system for taking notes. Most of the time he was the pure Golconda, what miners call a high-grader, working his way rapidly through vast mines of material and pocketing the richest bits.
That’s about all the energy I have today. Nasty head cold. I need to get me some sniffling sneezing coughing so I can rest medicine.
