Some years ago, as a step towards a solution of the problem, I published a "restoration" or "completion" of this picture in the "Field" (May 13th, 1911), and asked for criticisms and suggestions from the readers of that journal. I had no difficulty as to the completion of the biggest stag by drawing in his haunches and hind-legs, but the completion of the head and antlers of the smaller stag–and still more the calling into being of the entire calf as an inference from his or her suspended hind-feet and hoofs alone–were not easy tasks. I consulted many authorities and some instantaneous photographs, but I was not satisfied with the pose I finally suggested for the calf nor with the "points" assigned by my draughtsman to the antlers of the smaller stag. Some interesting suggestions were made in reply to my appeal by readers of the "Field." Those which seemed to me of conclusive weight and value were offered by Mr. Walter Winans, who combines the qualifications of a great observer of big game with those of a great artist. In the restoration now given in Fig. 5 I have profited by Mr. Walter Winans' criticism and have been especially glad to make use of the spirited sketch made by him for my benefit, and published in the "Field" of 1911, of a red-deer calf when hopping along with all the feet together, a movement known as "buck-jumping." "Of course," writes Mr. Winans, "this is quite different to the bronco-pony's action when trying to get rid of a rider. In the case of this kind she does not come down with a jar–but as she lands bends her knees and hocks simultaneously and then straightens them, also simultaneously, bounding in the air with bent back, tail curled tight on back, head thrown back, and ears forward; she never puts her fore-legs, either knee or fetlock, beyond her shoulder in this action." These words of Mr. Winans and his outline sketch of the buck-jumping calf precisely realize what the little hanging legs of the rubbed-out calf had been, as it were, urging my tired brain to recall and visualize. I am convinced that Mr. Winans' sketch gives the completion of the picture as drawn by the artist of the Lortet cavern, and satisfies the demand made by the gracefully suspended limbs shown in the incompletely preserved original. And so I have used it in my final restoration here given in Fig. 5. The following letter by Mr. Winans, giving valuable comments on the Lortet picture, was published in the "Field," and will assist others in appreciating its significance: it enabled me to get the middle stag's antlers correctly drawn. I have omitted a few lines referring to defects in the original restoration–now corrected.
