Passing from the mental to the bodily characteristics of hawks, we find that occasionally two hawks are so alike that it is almost impossible to distinguish them except by their jesses, while others of the same kind and sex are so dissimilar that a stranger may find it difficult to believe that they do not belong to different species. There are, naturally enough, good and bad hawks of every shape, size, and colour; and it would be very rash to pronounce off-hand at the first sight of one that she is worth more than any other. Nevertheless there are certain peculiarities which are found in the average of instances, taking many together, to belong more commonly to the best hawks, and others which in the great majority of cases betray the bad performer. These have always been remarked. They are mentioned in many ancient books, written in many languages; and there can be no doubt that after taking a good look at several individuals, an experienced judge will pick out those which he would prefer to possess if he had the choice. John Barr told me upon this subject a rather pleasant story. He was travelling southwards with a large number of hawks by train, when at an intermediate station he met with the late Prince Dhuleep Singh, who during a great part of his life was a most enthusiastic and successful falconer, by whom Barr was at one time employed. The Prince immediately inspected the hawks, which, I believe, were the same that were afterwards flown at Epsom, and in the course of conversation pointed out in their order the hawks which were likely to do best. The falconer mentally noted the selection thus made, and afterwards found that it was accurately justified by the result. It is somewhat curious that the same characteristics which in one species of hawks mark out an individual for admiration or the reverse, are mostly found to serve a like purpose in the other species. The following short remarks, therefore, unless when otherwise specified, may be taken as applying to hawks in general.
