To keep members of the _Zentralverein_ in touch with the movement and furnish newspapers with reports and items of information Hartwich had started a periodical, _Körper und Geist_, to be issued at irregular intervals. Only five numbers were actually published, the first in the spring of 1883 and the last in April of 1886. In his address at the organization of the society he had referred to the educational value which the English attribute to their games, and to the obligatory school games in Brunswick. He wrote to Koch at Brunswick, requesting a few lines from him on the subject of English games for German playgrounds, having in mind already as part of the program for his _Volks-_ and _Kinderfeste_ competitions in running, swimming, throwing the spear and the discus, wrestling, football, cricket, etc. Koch replied under date of November 1, 1883, with a recital of his own experience.[97] The _Vereine für Körperpflege_ were largely confined to Rhenish Prussia and Westphalia, a fact explained by the support which newspapers in these provinces, and notably the _Kölnische Zeitung_, gave to the movement. The membership, in both size and character, and the sums contributed fell short of what had been expected, and proved that a considerable portion of the public remained to be won over. Some teachers of gymnastics were hearty and loyal in their coöperation, but not a few _Turnvereine_ and leaders in the national _Turnerschaft_ adopted an attitude of apathy, or of positive opposition. “Into the open” was the cry of Hartwich, and he seemed to them to ignore, or not to appreciate, the solid achievements of the followers of Jahn and Spiess. There were many, too, who protested against the importation of English games and athletic sports in seeming disparagement of German _Turnen_ and native games. The early and tragic death of Hartwich—he was shot in a duel and died December 1, 1886—brought with it the collapse of the _Zentralverein_, for no other leader possessed of equal skill and courage came forward to take his place.
