But this pedagogical rigour was promptly offset by a return of her natural kindliness, a jesting word, a pleasantry, an affectionate term intended to prevent the discouragement of a pupil who often was guilty of nothing worse than thoughtlessness.
Under her firm and able guidance, the school achieved success. Many of her graduate pupils attained an honourable career in painting, and if no name worthy of being remembered is included among the whole number, the reason is that genius cannot be manufactured and that it was not within the power of Rosa Bonheur to give to her young pupils something of herself.
In 1860, the great artist, being overburdened with work and unable to carry on simultaneously the instruction and practice of her art, resigned her position as director. The school passed into the hands of Mlle. Maraudon de Monthycle, who won distinction as a director, but did not succeed in making the name of Rosa Bonheur forgotten.
The time of her retirement as professor of the school of design coincides with that of her installation at By. After having in a measure obeyed the paternal tradition of repeated removals, she was this time definitely established. It was destined to be her last residence; and it certainly was an attractive place, that great chateau of By, with its broad windows and its original style, which called to mind certain dwellings in Holland. And what a delightful setting it had in the shape of the forest of Fontainebleau, so varied in aspect, so rich in picturesque corners, so alluring with the beauty of its dense woodlands, and the poetry of its open glades!
Rosa Bonheur was always passionately enamoured of nature, of the entire work of creation. She adored animals neither more nor less than she loved beautiful trees and broad horizons; she went into ecstacies before the splendour of the rising sun which day by day brings a renewed thrill of life to all things and creatures; and it was equally one of her joys to watch the diffused light spreading softly through a misty haze over the slumbering earth.
Rosa Bonheur had no sooner withdrawn to the solitude of By than she sought, as we have already seen, to become forgotten, in order to devote herself exclusively to the innumerable tasks which incessant orders from England and America demanded of her. She planned for herself a laborious and tranquil existence, rendered all the pleasanter through the devoted and watchful affection of her old friend, Mlle. Nathalie Micas, who lived with her. We have seen that she came out of her voluntary obscurity in 1867 to the extent of sending a few pictures to the Universal Exposition. From this date onward she ceased to exhibit, and no other canvas bearing her signature was seen in public until the Salon of 1899, which was the year of her death.
Relieved of all outside interruption, Rosa Bonheur worked with indefatigable energy. Yet she could hardly keep pace with the demands of her purchasers, who were constantly increasing in number and constantly more urgent. Her paintings had acquired a vogue abroad and brought their weight in gold. Certain pictures brought speculative prices in America even before they were finished and while they were still on the easel at By. At this period, it may be added, everything which came from the artist’s brush possessed an incomparable and masterly finish. Never a suggestion of weakness in design even in her most hastily executed canvases. I must at once add that hasty canvases are extremely rare in the life work of Rosa Bonheur; she had too high a sense of duty to her art and too great a respect for her own name to slight any necessary work on a canvas. Certain pictures appear to have been done rapidly solely because the artist possessed among her portfolios fragmentary studies made from nature and drawn with scrupulous care, and all that she needed to do was to transfer them to her canvas.
From the host of works that the artist put forth at this period, we may cite: 1865, Changing Pasture, A Family of Roebuck; 1867, Kids Resting; 1868, Shetland Ponies; 1869, Sheep in Brittany; 1870, The Cartload of Stones.
The war of 1870 brought consternation to her patriotic soul. She suffered cruelly from the ills which had befallen her country. Generous by nature and a French woman to her inmost fibre, she did her utmost to relieve the suffering that she saw around her as a result of the Prussian invasion. She spoke words of comfort to the peasants and aided them with donations, distributing bags of grain that were sent to her by her friend Gambard, at this time consul at Odessa.
