Only the hours of instruction fared badly, and Froebel felt that he needed a man of fully developed strength in order to give the proper foundation to the instruction of the boys who were entrusted to his care. He knew a man of this stamp in the student F. A. Wolfs, whose talent for teaching had been admirably proved in the Bendemann family. "Langethal," as the first pupil describes him, was at that time a very handsome man of five-and-twenty years. His brow was grave, but his features expressed kindness of heart, gentleness, and benevolence. The dignity of his whole bearing was enhanced by the sonorous tones of his voice--he retained them until old age--and his whole manner revealed manly firmness. Middendorf was more pleasing to women, Langethal to men. Middendorf attracted those who saw, Langethal those who heard him, and the confidence he inspired was even more lasting than that aroused by Middendorf. What marvel that Froebel made every effort to win this rare power for the young institute? But Langethal declined, to the great vexation of Middendorf. Diesterweg called the latter "a St. John," but our dear, blind teacher added, "And Froebel was his Christus." The enthusiastic young Westphalian, who had once believed he saw in this man every masculine virtue, and whose life appeared emblematical, patiently accepted everything, and considered every one a "renegade" who had ever followed Froebel and did not bow implicitly to his will. So he was angered by Langethal's refusal. The latter had been offered, with brilliant prospects for the present and still fairer ones for the future, a position as a tutor in Silesia, a place which secured him the rest he desired, combined with occupation suited to his tastes. He was to share the labour of teaching with another instructor, who was to take charge of the exact sciences, with which he was less familiar, and he was also permitted to teach his brother with the young Counts Stolberg. He accepted, but before going to Silesia he wished to visit his Keilhau friends and take his brother away with him. He did so, and the "diplomacy" with which Froebel succeeded in changing the decision of the resolute young man and gaining him over to his own interests, is really remarkable. It won for the infant institute in the person of Langethal-- if the expression is allowable--the backbone. Froebel had sent Middendorf to meet his friend, and the latter, on the way, told him of the happiness which he had found in his new home and occupation. Then they entered Keilhau, and the splendid landscape which surrounds it needs no praise.
