So there was built, close by that detestable little House No. 1, another little house, called House No. 2. That was a comfortable house! It had windows on the side opposite to its door, so that a fine trade wind played through it. It was cool. It had a nice clean cot in it, with steam-disinfected bedding. It would have been an excellent house for a consumptive to get better in. It was a thoroughly sanitary little house. Half way across the inside of it was a screen, from top to bottom, a fine-meshed screen that the tiniest mosquito found it impossible to fly through. At 12 o’clock noon on the twenty-first of December in 1900, this John J. Moran (who was a hog for these tests) “clad only in a nightshirt and fresh from a bath” walked into this healthy little house. Five minutes before Reed and Carroll had opened a glass jar in that room, and out of that jar flew fifteen she-mosquitoes, thirsty for blood, whining for a meal of blood, and each and every one of those fifteen mosquitoes, had fed, on various days before--on the blood of yellow-faced boys in the hospital of Las Animas. Clad only in a nightshirt and fresh from a bath, Moran--who knows of him now?--walked into the healthy little room and lay down on his clean cot. In a minute that damned buzzing started round his head, in two minutes he was bitten, in the thirty minutes he lay there he was stabbed seven times--without even the satisfaction of smashing those mosquitoes. You remember Mr. Sola, whom Grassi tortured--he probably had his worried moments--but all Mr. Sola had to look forward to was a little attack of malaria and a good dose of curative quinine to get him out of it. But Moran? But John J. Moran was a hog for such tests! He was back there at four-thirty the same afternoon, to be bitten again, and once more the next day--to satisfy the rest of the hungry she-mosquitoes who hadn’t found him the first day. In the other room of this house, with only a fine-meshed but perfect wire screen between them and Moran--and the mosquitoes--lay two other boys, and those two boys slept in that house safely for eighteen nights. But Moran?
