【正文】 s a Lewis gun, Robert Jordan thought. Do you know anything about a machine gun? he asked the old man. Nada, said Anselmo. Nothing. And thou? to the gypsy. That they fire with much rapidity and bee so hot the barrel burns the hand that touches it, the gypsy said proudly. Every one knows that, Anselmo said with contempt. Perhaps, the gy psy said. But he asked me to tell what I know about a _m 醧 uina_ and I told him. Then he added, Also, unlike an ordinary rifle, they continue to fire as long as you exert pressure on the trigger. Unless they jam, run out of ammunition or get so hot they melt, Robert Jordan said in English. What do you say? Anselmo asked him. Nothing, Robert Jordan said. I was o a pistol. He kept waving the pistol and shouting at them and we were all shooting at him but no one hit him. Then some troops lay down and menced firing and the officer walked up and down behind them with his pistol and still we could not hit him and t he _m 醧 uina_ could not f ire on him because of the position of the train. This officer shot two men as they lay and still they would not get up and he was cursing them and finally they got up, one tw o and three at a time and cam e running toward us and the train. Then they lay flat again and fired. Then we left, with the _m 醧 uina_ still speaking over us as we left. It was then I found the girl where she had run from the train to the rocks and she r an with us. It was those troops who hunted us until that night. It must have been something very hard, Anselmo said. Of much emotion. It was the only good thing we have done, said a deep voice. What are you doing now, you lazy drunken obscene unsayable son of an unnameable unmarried gypsy obscenity? What are you doing? Robert Jordan saw a woman of about fifty almost as big as Pablo, almost as wide as she was tall, in blac k peasant skirt and waist, with heavy wool soc ks on heavy legs, black ropesoled shoes and a brown face like a model for a granite monument. She had big but nicelooking hands and her thick curly black hair was twisted into a knot on her neck. Answer me, she said to the gypsy, ignoring the others. I was talking to these rades. This one es as a dynamiter. I know all that, the _mujer_ of Pablo said. Get out of here now and relieve Andr 閟 who is on guard at the top. _Me voy_, the gypsy said. I go. He turned to Robert Jordan. I will see thee at the hour of eating. Not even in a joke, said the woman to him. Three times you have eaten today according to my count. Go now and send me Andr 閟 . _Hola_, she said to Robert Jordan and put out her hand and smiled. How are you and how is everything in the Republic? Good, he said and returned her strong hand grip. Both with me and with the Republic. I am happy, she told him. She was looking into his face and smiling and he noticed she had fine gray eyes. Do you e for us to do another train? No, said Robert Jordan, trusting her instantly. For a bridge. _No es nada_, she said. A bridge is nothing. When do we do another train now that we have horses? Later. This bridge is of great importance. The girl told me your rade who was with us at the train is dead. Yes. What a pity. Never have I seen such an explosion. He was a man of talent. He pleased me very muc h. It is not possible to do another train now ? There are many men here now in the hills. Too many. It is already hard to get food. It would be better to get out. And we have horses. We have to do this bridge. Where is it? Quite close. All the better, the _mujer_ of Pablo said. Let us blow all the bridges there are here and get out. I am sic k of this place. Here is too much concentration of people. No good can e of it. Here is a stagnation that is repugnant. She sighted Pablo through the trees. _Borracho!_ she called to him. Drunkard. Rotten drunkard! She turned back to Robert Jordan cheerfully.
