He selected in each school a teacher who was interested in the subject (usually the athletic instructor) as superintendent of shooting, and in each class four boys as sergeant-instructors. The superintendent and these boys were carefully instructed by Captain Corwin in the theory and practice of shooting, so as to make them competent instructors. The system adopted varied in the different schools. Most of them preferred to use school hours for the purpose. In these schools, usually when each class was sent to the gymnasium for physical exercise, squads of boys in rotation were detached to practice their firing under the immediate direction of a sergeant-instructor, and the general direction of the superintendent of shooting, the whole being carefully supervised by Captain Corwin. Some schools preferred to have their shooting after school hours, in which case, however, it was carried on under the same general principle. Captain Corwin was of the opinion that the former method was the most satisfactory, although the Morris High School, which won the Whitney trophy in 1906, adopted the latter method. The league established a marksmanship badge, to be awarded, as in the National Guard and in the Army, to each boy who annually showed satisfactory proficiency in shooting. The qualifying score first adopted for this badge was 40 out of a possible 50 "off-hand." It was found almost immediately that the boys were shooting so well that it was necessary to raise the standard, which was therefore increased to 42 and later to 43. The following is a list of the number of boys who qualified as marksmen in their respective schools during the year 1906: Boys' High School 45 Bryant High School 18 Commercial High School 6 Curtis High School 24 De Witt Clinton High School 23 Morris High School 16 Erasmus Hall High School 15 Manual Training High School 23 High School of Commerce 19 Stuyvesant High School 8 Total 197 The qualifying score has now been raised to 44. The Brooklyn Eagle assumed the expense of manufacturing and presenting these badges, which consisted of a Maltese cross having crossed rifles, the seal of the league, which is the "Winged Victory," in the center, the whole being suspended from a bar with the word "Marksman" on it, and the date. During the spring of 1906 a large number of interscholastic competitions were held. These were found valuable, not only in broadening the boys' ideas in respect to shooting, but in helping their nerve in competitions.
