The historian's spirit should not be without a touch of the poetical; it needs, like poetry, to employ impressive and exalted tones, especially when it finds itself in the midst of battle array and conflicts by land or sea; it is then that the poetic gale must blow to speed the vessel on, and help her ride the waves in majesty. But the diction is to be content with _terra firma_, rising a little to assimilate itself to the beauty and grandeur of the subject, but never startling the hearer, nor forgetting a due restraint; there is great risk at such times of its running wild and falling into poetic frenzy; and then it is that writers should hold themselves in with bit and bridle; with them as with horses an uncontrollable temper means disaster. At these times it is best for the spirit to go a-horseback, and the expression to run beside on foot, holding on to the saddle so as not to be outstripped. As to the marshalling of your words, a moderate compromise is desirable between the harshness which results from separating what belongs together, and the jingling concatenations--one may almost call them-- which are so common; one extreme is a definite vice, and the other repellent. Facts are not to be collected at haphazard, but with careful, laborious, repeated investigation; when possible, a man should have been present and seen for himself; failing that, he should prefer the disinterested account, selecting the informants least likely to diminish or magnify from partiality. And here comes the occasion for exercising the judgement in weighing probabilities. The material once complete, or nearly so, an abstract should be made of it, and a rough draught of the whole work put down, not yet distributed into its parts; the detailed arrangement should then be introduced, after which adornment may be added, the diction receive its colour, the phrasing and rhythm be perfected. The historian's position should now be precisely that of Zeus in Homer, surveying now the Mysians', now the Thracian horsemen's land. Even so _he_ will survey now his own party (telling us what we looked like to him from his post of vantage), now the Persians, and yet again both at once, if they come to blows. And when they are face to face, his eyes are not to be on one division, nor yet on one man, mounted or afoot--unless it be a Brasidas leading the forlorn hope, or a Demosthenes repelling it; his attention should be for the generals first of all; their exhortations should be recorded, the dispositions they make, and the motives and plans that prompted them. When the engagement has begun, he should give us a bird's-eye view of it, show the scales oscillating, and accompany pursuers and pursued alike.
