An even bigger challenge emerged this year as a jury ordered the Scouts to pay $18.5 million in damages to a man who had been abused by a scout leader as a boy. The trial focused renewed attention on the secret files that the Scouts’ national office in Texas has kept for more than 70 years of claims of sexual abuse by troop leaders and volunteers.  Now, as the organization tries to rebuild its image and its membership, it has been forced to make a priority of addressing that problem, with a plan that it calls “youth protection.”  Under Robert Mazzuca, who took the helm of the Scouts three years ago as chief executive, the group has taken several steps to try to reassure parents that their children are safe. These include hiring a full-time youth protection director, Michael Johnson, a former police detective who is an expert on child abuse investigation and prevention.  Mr. Mazzuca said in an interview that scouting remained grounded in the core values of the Boy Scout Law (trustworthy, loyal, helpful) but that the organization needed better ways to communicate its relevance.  “We have allowed ourselves to be defined by others for a long period of time, and it’s time for us to be in charge of our own definition,” he said.  “Anything 100 years old has earned the right to a little arthritis,” he said, but added that this organization had become “stodgy and bureaucratic.”  “We need to be more nimble,” he said. “Scouts still have a wonderful story to tell.”  The jamboree here is a testament to the many ways in which the Scouts have adapted. Spread across hundreds of acres of this dusty military base, the scout encampment still offers boys the chance to partake in the activities that their fathers and grandfathers enjoyed — fly-fishing, reading a compass, rustling up a meal. Many boys devote hours to the low-tech pursuit of swapping scout patches with the same fervor of Wall Street traders.  But this is not your father’s jamboree. Among the sprawling areas here is a technology center with robotics and a tent where boys can have their mouths swiped to take a sample of their DNA. Some boys sport lime-green hair to match the T-shirts of their non-dress uniforms, and most wear loose-fitting knee-length shorts, some surfer-dude cool with bright swirls.  Scouts also wear “smart bracelets” that allow them to go cashless as they buy soda and memorabilia. An inflatable mosque provides a place for Muslim scouts to worship. There are stations where scouts can recharge their cellphones as well as those offering free calls and time online. Despite these innovations, there has been less advancement on other fronts. The tens of thousands of scouts here were largely a homogenous group of white boys. A Scout study from a few years ago on “tapping into diverse markets” said that parents of African-Americans, Hispanics and Asians had “no emotional connection to scouting.” A documentary to be broadcast in August on PBS explores this concept as it follows black and Hispanic scouts from Harlem.  Mr. Mazzuca is trying to change that, with the Scouts making a major push among Hispanics, the largest-growing ethnic group in the country. “We used to just translate our material into Spanish words,” he said, “not linking them to things that are meaningful to Hispanics.” He said that focus groups showed that Hispanics viewed the Boy Scouts as “elite and unattainable.” And in setting up pilot programs, he said, he had to overcome concern that some potential scouts might be from illegal immigrant families.  In a pilot program in Fresno, Calif., Mr. Mazzuca said, the Scouts had doubled their Hispanic membership in nine weeks, though it is not clear yet how many will stay.  But the demographic group that seems to have drawn the most attention is young girls. When they turn 13 and have completed eighth grade, they can join the Boy Scouts’ Venturing program, where many of the leaders are women. But many are pushing for access for preteen girls.  Katrell Cooper, a 16-year-old venturer from Utah, who works at the BMX center here, turned up her nose at the Girl Scouts.  “I don’t want to sit around and make quilts and sell cookies,” she said after she expertly glided down a mountain-boarding course on which a few boys had tumbled. “I want to do stuff.”  The debate rages on scout Web sites over the perceived advantages and disadvantages of allowing younger girls. Would they be too much of a distraction? Or would their presence better prepare boys for the real world?  Several 15-year-old boys here said they would welcome girls into the Boy Scouts. “It would be more cool with them,” said Shane West from Jupiter, Fla. Why? “They’re girls.”  Rocky Spiker, from Utah, said girls would “keep us in line.” Ben Rosenbaum, from California, said, “Women deserve the same stuff as men do.”  The boys were practicing at a shooting range, where their instructor, Kelli Walters, 18, from Pennsylvania, who is certified by the National Rifle Association and is part of the Venturing program, had longed to join the Boy Scouts, a family tradition. She was bored with Girl Scouts.  Mr. Mazzuca said he wanted the Scouts to stay true to the organization’s roots of helping boys, especially at younger ages, to become good men, but he was open to discussions.  For now, he is focused on the jamboree, which holds its centennial celebration Saturday. The anniversary will be marked across the country, including in Times Square, where a display will offer canoe rides in an artificial river on Broadway.  Then for the Scouts, it will be back to finding a way out of the woods.  An article on Saturday about the Boy Scouts’ trying to rebuild their image and their membership misidentified the home state of a scout who attended the organization’s National Scout Jamboree last week at Fort A.P. Hill, Va., and said that “women deserve the same stuff as men do.” The scout, Ben Rosenbaum, is from California, not Utah.

The group is working to redefine itself amid falling numbers, a push for diversity and a knock on the door from girls.
