A Dissertation on Horses | Page 4

as a Horse of foreign extraction, we do not impute that equality of velocity to any innate quality in the half-bred Horse, because we can account for it by external causes: that is by an equality of the length, and extent of his levers and tendons. And when we consider a half-bred Horse running one mile, or more, with the same velocity as the other, and then giving it up, what shall we do? shall we say the foreigner beats him by his blood, or by the force and power of his tendons? or can we, without reproaching our own reason and understanding, impute that to be the effect of occult and hidden causes in the one of these instances and not in the other? both of which are demonstrated with certainty, and reduced to facts by the knowledge of anatomy and the principles of mechanics.
How many instances have we of different Horses beating each other alternately over different sorts of ground! how often do we see short, close, compact Horses beating others of a more lengthened shape, over high and hilly coursed, as well as deep and slippery ground; in the latter of which, the blood is esteemed much better, and whose performances in general are much better!
And how comes it to pass that Horses of a more lengthened shape, have a superiority over Horses of a shorter make, upon level and flat courses? Is this effected by the difference of their mechanical powers, or is it affected by the blood? if, by the latter, then this blood is not general, but partial only, which no reasoning man will be absurd enough to allow. But I much fear our distinctions of good and bad blood are determined with much partiality; for every jockey has his particular favourite blood, of which he judges from events, success, or prejudice: else, how comes it to pass, that we see the different opinions and fashions of blood varying daily! nay, we see the very same blood undergoing the very same fate; this year rejected, the next in the highest esteem; or this year in high repute, the next held at nothing. How many changes has the blood of Childers undergone! once the best, then the worst, now good again! Where are the descendants of Bay Bolton, that once were the terror of their antagonists! Did these prevail by the superiority of their blood, or because their power and their fabric was superior to the Horses of their time? If any one ask why Danby Cade was not as good a racer as any in the kingdom, the jockey could not impute this defect to his blood; but if it should be imputed to his want of proportion, surely it might be held for a true and satisfactory reason. How many revolutions of fame and credit, have all sportsmen observed in these HIGH-BRED families.
Numberless are the examples of this kind which might be quoted, but to account for this, one says, The blood is wore out for want of a proper cross; another tells us, That after having been long in this climate, the blood degenerates; but these reasons cannot be true, because we see the off-spring of all crosses, and of the most antient** families, occasionally triumphant over the sons of the very latest comers, the error then will not be found in the blood, or in the proper crossing; but the defect will be produced by the erroneous judgment of mankind, in putting together the male and female with improper shapes; and while we are lost and blinded by an imaginary good, the laws of nature stand revealed; and we by paying a proper attention thereto, and employing our judgment therein, might wipe this ignis fatuus from the mind, and fix the truth on a sure foundation. Our observation shews us, that on the one hand, we may breed Horses of foreign extraction too delicate, and too slight for any labour; and on the other hand, so coarse and clumsy, as to be fitter for the cart than the race. Shall we then wonder these cannot race, or shall we doubt that degrees of imperfection in the mechanism, will produce degrees of imperfection in racing! and when we find such deficient, shall we ridiculously impute it to a degeneracy of that blood, which once was in the highest esteem, or to the want of judgment in him who did not properly adapt the shapes of their progenitors!
Shall we confess this, or is the fault in nature? For though most philosophers agree, that innate principles do not exist, yet we know for certain, that in the brute creation, whose food is plain and simple, (unlike luxurious man) the laws of nature are, generally speaking, invariable and determined. If it should be asked why
