By 1910, Camp life and its programs remained much the same throughout the decade. A first-class athletic program and a variety of special events compensated for what Camp Eberhart did not have in the way of program areas. In his campfire stories Coop told about how Eberhart had one of the finest athletic staffs of any camp in the country. Knute Rockne and other well-known coaches as well as an Olympic medal winner assisted in Camp's instruction.

When Camp life required some additional excitement, the imagination of the leaders was the only limit, as the legends of the area were used for many such antics. One example was the "discovery" of Hesikia's treasure chest on July 4, 1911.

In 1912 Eberhart initiated Girls Camp under the supervision of the YWCA. A photo of the girls from that season shows 21 young women in long dresses. In 1913 Young Women's Camp ran from August 4-18 for girls 14 and over. Miss Moerdyke of the YWCA was the point of contact and the cost was $6.00 -- one dollar more per week than boy's camp. The brochure for the summer warns girls: "You are going camping, not to a summer hotel," and that "plain wash dresses will be suitable. A dark wool skirt (short), and a middy blouse is suggested for a camp costume. Many wear bloomers." In 1915 a total of 35 women were photographed on a camp pier.

By 1919 Girls Camp had divided into two camps: Business Girls from August 2-9 and Schoolgirls from August 11-23. They used their own honor system. Each day special stunts were planned such as hikes, picnics, corn roasts and athletic and aquatic contests.

Men's Camp was held in 1910 for senior members of the YMCA and their friends from August 1 to September 1. The "Senior Camp" as it was called by 1913, camped in tents and meals were served at regular hours by the self-service plan, "the same as in the boy's camp." There was no organized program during this special camp; however, they enjoyed fishing, boating and special events.

There was also a special High School Camp from August 26 to September 15 for boys 15 or older who were forewarned to "come determined to win a Brown Rag," adding that "the leadership will be the very best, the activity suitable to live boys, so come to have the time of your life."

During his July 4th address of the 1912 season, Mr. S. B. Pettingill spoke to the Camp about patriotism using the classic story, "A Man Without a Country" and examples from the Revolutionary War. His speech is included in The Three Rivers Kids by Frank Cheley.

The tents, which originally had dirt floors, had new cement floors by 1913. On the hill in front of the Lodge there were stones arranged in a large display reading "Camp Eberhart." The brochure for the season, boasting that "no two days in Camp will be just alike," listed Cheley in charge, assisted by Julius C. Brug with Mr. Miler and George Cooper running physical work and Mr. Helman heading the educational work.

There were four medals that could be earned, in addition to the regular Honor System. Four areas were covered: spirit, aquatics, athletics and all-around development. Winners for the 1915 season were: J. Edwin Dean (Leader's Medal); Donald C. Johnson (Aquatic Medal); Donald Jones (Athletic Medal); and Arthur Crosby (All Round Development Medal). They were all from South Bend, except for Jones, who lived in Glencoe, Illinois. Winners received the Camp letter "E" and a round medal depicting the tents, beach and Camp triangle with the "E" in the center.

During the 1915 season, Camp was without either of its two top leaders. Cheley departed for a new job as Boy's Work Director at the St. Louis (Missouri) YMCA and Coop was still at Springfield College, finishing up his senior year. The 1916 season saw P. Walter Kamaiopili as the South Bend Y's Boy's Work Director and as Eberhart Director. Coop was back this summer as his assistant. The 1916 Camp brochure reads: "Our patrons will be interested in knowing that Mr. G. A. Cooper, formally assistant physical director and after August 1 to become Boy's Work Director, will have charge of camp activities, such as games, swimming, tennis, etc, from July 1 on." (Kamaiopili also served as director for the 1917 and 1919 seasons.) In 1916 the annual medals became known as the E.G. Eberhart Medals, in honor of Harris Eberhart's father who committed suicide the previous year.

The Honor System for this season was the same as before; however, the schedule was slightly altered. At 9 a.m. was letter writing, nature study and recreation; at 10 work began on the honor system and at 11 was morning swim. All campers learned how to swim and were required to pass the U.S. Life Saving Test. In addition to the regular rowboats, this summer featured a 25-foot "Old Town War Canoe" with a seating capacity of ten.

1918, under the leadership of J. Russel Jontz, saw the annual Fourth of July campfire at a height of 51 feet. Each year, Camp tried to beat the previous summer's record. Winners of the 1918 Eberhart Awards were: Harry Hompson (Leader's Medal); Phillip Druiding (Aquatics); George Robinson (Athletics) and Francis Barada (All Round Development).

R. A. Overholser directed Camp in 1919. A poster advertising the new season listed some new program areas: archery and woodcraft. This may have signaled the end of the 10-year request by the Eberhart family that no changes be made from Harris' original concept.

The 1919 Honor System was based on the American Standard Program, developed around four areas: physical, mental, social and spiritual. There were still Brown and Green Rags; however, there were different requirements for each rag and for the four basic areas depending on the camper's age. A 12-year-old camper could earn the first degree in both rags, in which case he/she could also wear the Prospector's chevron. The camper would have to wait until the following summer to attempt the second degree for both rags and could then wear the Trail Blazer chevron.

Requirements for the physical skills area for a 12-year old:

Brown Rag: 1. Participate in 85 percent of mass and group games while at camp. 2. Attend all drills (smilingly) 3. Swim 50 yards. 4. Score at least 35 points in the 60-yard potato race for your weight.

Green Rag: 1. Take part in regular tournaments. 2. Swim 100 yards. 3. Score at least 24 points in high jump for your weight. 4. Give evidence of the following habits of your daily life: a. fixed hour for rising and b., cleaning the teeth once a day.

In 1919, Camp Eberhart sat on 18 acres. The Lodge finally had hot and cold running water and a three acre Camp Farm provided campers with fresh vegetables. Each camper was required to work in the "garden" daily. The waterfront had a "live springboard" and a 15-foot high dive mounted on a floating raft. A number of large war canoes also dotted the shore. Summer school, taught by Lieutenant Finch was offered in all subjects for 7th and 8th grades and for high school math, history and commercial arithmetic. Finch was a DePauw University grad and taught school in South Bend. A certificate was awarded for campers to prove that they passed their exams while at Camp. A scholarship medal was now awarded to the camper who excelled in summer studies.

Coop, now the Y's Physical Director, continued running physical activities at Camp and assisted the camp directors until he, himself, was named director of Eberhart in 1925.
