Young Promising Wrestlers.

    A Tokyo contemporary reports that there are in the capital two young and promising wrestlers, one called Adachiyama and the other Kohitachi, who have not yet appeared in the ring in consequence of their being only mere boys. The former is the eldest son of one Masutaro Sekine living in Osato-mura, Kita-Adachi district, Saitama prefecture, and his real name is Seisaku.  He is now 14 years old, but he is said to weigh as much as 22 kwan 500 me (about 190 pounds) and to possess a bodily frame powerfully built and of dimensions in proportion to his weight. This year the promising lad in question was, under the professional name of Adachiyama, admitted as one of the disciples of the retired wrestler Tomozuna.
    Another future wrestler is the third son of one Seihachi Yoshida living in Obanmachi, Yotsuya, Tokyo, whose real name is Yoshitaro. He is also 14 years old this year, weighs 19 kwan 500 me (about 160 pounds), and was adopted a year or two ago by the wrestler Hitachiyama as his son-in-law. He now goes by the professional name of Kohitachi.
