Mr. Polonceau has unremittingly persevered in the improvement so immediately effected, and has proved during the several years which have elapsed since the first experiment in the year 1822, that an entire satisfactory result in the union of the most essential qualities of down, abundance, length, fineness, lustre, and softness, was accomplished by the first cross, without any return having ensued to the individual characters of either of the primitive races, and in consequence, he has since constantly propagated the produce of that cross among themselves, careful only of preserving animals entirely white and of employing for propagation those bucks which had the down in the greatest quantity and of the finest quality with the smallest proportion of hair.
In 1826; the "Societie Royale et Centrale d'Agriculture de Paris" acquainted with the interesting result of M. Polonceau's flock, being at that time in the third generation, and considering that the down of this new race was more valuable than that of the East, and that it was the most beautiful of filaceous materials known, as it combines the softness of Cashmere with the lustre of silk, awarded him their large gold medal at their session, 4th April, 1826, and nominated him a member of their society in the following year.
In 1827, at the exhibition of the produce of National Industry, the jury appointed to judge the merits of the objects exposed, also awarded him their medal.
At present the animals are in the twelfth generation, their health and vigor, the constancy of their qualities, and abundance of their down without any degeneration, prove that this new race may be regarded as one entirely fixed and established, requiring solely the care that is generally observed with valuable breeds; that is to say, a judicious choice of those employed for their reproduction, and in such a climate as New South Wales it may be reasonably expected that the brilliant qualities of their down may yet be improved as has been so eminently the case with the wool of the merino and Saxon sheep imported there.
M. Polonceau has goats that have yielded as many as thirty ounces of the down, in one season, and he states that the whole
