_Absurdity_.--They were widening the road near Lord Claremont's seat as we passed. A number of cars were drawn up together at a particular point, where we also halted, as we understood they were blowing a rock, and the _shot_ was expected presently to go off. After waiting two minutes or so, a fellow called out something, and our carriage as a planet, and the cars for satellites, started all forward at once, the Irishmen whooping and crying, and the horses galloping. Unable to learn the meaning of this, I was only left to suppose that they had delayed firing the intended _shot_ till we should pass, and that we were passing quickly to make the delay as short as possible. No such thing. By dint of making great haste, we got within ten yards of the rock when the blast took place, throwing dust and gravel on our carriage, and had our postillion brought us a little nearer (it was not for want of hallooing and flogging that he did not), we should have had a still more serious share of the explosion. The explanation I received from the drivers was, that they had been told by the overseer that as the _mine_ had been so long in _going off_, he dared say we would have time to pass it--so we just waited long enough to make the danger imminent. I have only to add that two or three people got behind the carriage, just for nothing but to see how our honours got past. Went to the Oil Gas Committee[7] this morning, of which concern I am president, or chairman. It has amused me much by bringing me into company with a body of active, business-loving, money-making citizens of Edinburgh, chiefly Whigs by the way, whose sentiments and proceedings amuse me. The stock is rather low in the market, 35s. premium instead of £5. It must rise, however, for the advantages of the light are undeniable, and folks will soon become accustomed to idle apprehensions or misapprehensions. From £20 to £25 should light a house capitally, supposing you leave town in the vacation. The three last quarters cost me £10, 10s., and the first, £8, was greatly overcharged. We will see what this, the worst and darkest quarter, costs.
