As a general rule, it is safe to say that the best prophecies are those which the sages remember after the event prophesied of has come to pass, and remind us that they have made long ago. Those who, are rash enough to predict publicly beforehand commonly give us what they hope, or what they fear, or some conclusion from an abstraction of their own, or some guess founded on private information not half so good as what everybody gets who reads the papers,--never by any possibility a word that we can depend on, simply because there are cobwebs of contingency between every to-day and to-morrow that no field-glass can penetrate when fifty of them lie woven one over another. Prophesy as much as you like, but always hedge. Say that you think the rebels are weaker than is commonly supposed, but, on the other hand, that they may prove to be even stronger than is anticipated. Say what you like,--only don't be too peremptory and dogmatic; we know that wiser men than you have been notoriously deceived in their predictions in this very matter. Ibis et redibis nunquam in bello peribis. Let that be your model; and remember, on peril of your reputation as a prophet, not to put a stop before or after the nunquam. There are two or three facts connected with time, besides that already referred to, which strike us very forcibly in their relation to the great events passing around us. We spoke of the long period seeming to have elapsed since this war began. The buds were then swelling which held the leaves that are still green. It seems as old as Time himself. We cannot fail to observe how the mind brings together the scenes of to-day and those of the old Revolution. We shut up eighty years into each other like the joints of a pocket-telescope. When the young men from Middlesex dropped in Baltimore the other day, it seemed to bring Lexington and the other Nineteenth of April close to us. War has always been the mint in which the world's history has been coined, and now every day or week or month has a new medal for us. It was Warren that the first impression bore in the last great coinage; if it is Ellsworth now, the new face hardly seems fresher than the old. All battle-fields are alike in their main features. The young fellows who fell in our earlier struggle seemed like old men to us until within these few months; now we remember they were like these fiery youth we are cheering as they go to the fight; it seems as if the grass of our bloody hillside was crimsoned but yesterday, and the cannon-ball imbedded in the church-tower would feel warm, if we laid our hand upon it.
