Legend has it that when the Romans defeated the Carthaginians in the Third Punic War in 146 BC, the victorious Romans sacked Carthage plowing under the crops and sowing salt into the soil, rendering the land ruined. Probably by pouring seawater into the farmer’s fields because salt was valuable at the time. I learned this in middle school history in Mr. Burn’s class. It was a harsh punishment and the lessons of history are full of harsh penalties and punishments, of people acting with vengeance instead of reaching out and pulling up. Sadly, history repeats itself – repeatedly.
Last week I was in Mississippi to visit my step-mom and I had to leave a day early because of Octavia. Octavia was the winter storm that wreaked havoc across America’s midsection at the beginning of last week. I decided I couldn’t risk being stranded in Oxford or at the Memphis airport on Monday and flew out Sunday evening. It was a good decision because all of Monday’s flights from Memphis to Chicago and the first two flights Tuesday were cancelled. I got home and it was bitter cold here but the roads were dry, in part to large doses of salt when it has snowed. The roads are coated with a white salt brine that seems to leach from the road and sidewalks until the spring rains wash it all away.
Enough of the history and the weather lesson and on to science. Continue reading Salt from sand
