The Martha’s Vineyard Rod and Gun Club, more than 200 strong, will report, in case of emergency, as a shotgun brigade, according to a resolution adopted by the club on Wednesday night. The club discussed possibilities of an invasion with grim and practical earnestness before adopting the resolution, taking a report of the arms owned by its membership which consist of at least one shotgun to a man and a number of rifles. Given any sort of break, the club felt that its membership could add considerably to the unpleasant situation of an enemy should one appear.
