Edgar was the first to fasten a rope round his body , and while this was held by his companions he was to get out on the window-sill and throw a grapnel over the ridge and pull himself up by the rope attached to it . The others were to fasten the rope round their bodies at distances of twenty feet apart , so that if one slipped down the others could check him .
