Soon after the prisoners have settled to sleep, from the different walls there starts a downward immigration of myriads of parasitical insects. One cannot possibly conceive the innumerable number of bed-bugs, some of enormous size, lice of all classes, fleas, mosquitoes and cock-roaches. They assure me that the prisoners become accustomed to all these parasites and they do not heed them. The truth is that besides myself I did not notice anybody paying any attention to them. Only three persons were privileged to use cots; the head keeper and two head men. I could not find a place to lie down. The head keeper saw me standing and understood the reason of my perplexity and authorized me to sleep under his cot. At first I took this offer as an insult; later I understood the full value of that concession which was not gratis but cost me 25 cents. It had just struck nine at the prison clock when suddenly and accidentally all the electric lights went out. The darkness was absolute. Immediately a formidable roar arose from that mob and a fearful struggle began. There were heard shouts of hatred, fearsome lamentations, blasphemies, the voices of the head men trying to impose order and shouting to the prisoners to keep silent, but without avail. It was undescribable uproar. Soon afterwards footsteps of soldiers were heard nearing the door. An employé arrived with the escort bringing a lantern along. He opened the grated door with a great deal of noise and gave order to the soldiers to fire in case of further disorder. Then everything was silent as if by incantation. The turnkey asked for the oil lamps hanging on the walls, lighted them and distributed them to the head men to place them in their corresponding places. From time to time the silence was interrupted by some stifled groans. The turnkey ordered the formation of rows to make ready for the roll call. They brought the register and the prisoners going into the corridor after their names being called. Some did not appear, others answered in a dying voice. All the prisoners able to do so went back to rest. There were three dead and seventeen wounded. Who are the authors of these crimes? They have so far not discovered them, and those who know the way of the prison claim that they never will be found. The prisoners no matter how strict the vigilance and how often they search them succeed in hiding pieces of bones which form part of the meat rations, and these bones they sharpen against the stones of the floor until they become as sharp and pointed as daggers. Those are the weapons used in their fights. They also employ scissors, and spoons and other instruments which are used in their different trades and which they manage to steal.
