Here the scene is beautiful. The van rests upon a high embankment, with a pool surrounded by pine-trees on the right, green fields on the left. Cattle are feeding quietly about. The air sings with birds. The chestnut-leaves sparkle. Frogs whistle in the warm spring morning. The regiment groups itself along the bank and the cutting. Several Marylanders of the half-price age--under twelve--come gaping up to see us harmless invaders. Each of these young gentry is armed with a dead spring frog, perhaps by way of tribute. And here--hollo! here comes Horace Greeley _in propria persona!_ He marches through our groups with the Greeley walk, the Greeley hat on the back of his head, the Greeley white coat on his shoulders, his trousers much too short, and an absorbed, abstracted demeanor. Can it be Horace, reporting for himself? No; this is a Maryland production, and a little disposed to be sulky. After a few minutes' halt, we hear the whistle of the engine. This machine is also an historic character in the war. Remember it! "J. H. Nicholson" is its name. Charles Holmes drives, and on either side stands a sentry with fixed bayonet. New spectacles for America! But it is grand to know that the bayonets are to protect, not to assail, Liberty and Law. The train leads off. We follow, by the track. Presently the train returns. We pass it and trudge on in light marching order, carrying arms, blankets, haversacks, and canteens. Our knapsacks are upon the train. Fortunate for our backs that they do not have to bear any more burden! For the day grows sultry. It is one of those breezeless baking days which brew thunder-gusts. We march for some four miles, when, coming upon the guards of the Massachusetts Eighth, our howitzer is ordered to fall out and wait for the train. With a comrade of the Artillery, I am placed on guard over it. ON GUARD WITH HOWITZER NO. TWO HENRY BONNELL is my fellow-sentry. He, like myself, is an old campaigner in such campaigns as our generation has known. So we talk California, Oregon, Indian life, the Plains, keeping our eyes peeled meanwhile, and ranging the country. Men that will tear up track are quite capable of picking off a sentry. A giant chestnut gives us little dots of shade from its pigmy leaves. The country about us is open and newly plowed. Some of the worm-fences are new, and ten rails high; but the farming is careless, and the soil thin. Two of the Massachusetts men come back to the gun while we are standing there. One is my friend Stephen Morris, of Marblehead, Sutton Light Infantry. I had shared my breakfast yesterday with Stephe. So we refraternize.
