Members of the Dartmouth hockey team are figuring a little on how much is superstition and how much is fact in the unluckiness of the number 13. The team that was beaten in the Boston Arena by Yale, score, 7-2, set out for the game on Friday, the 13th. There were 13 men in the party,,which traveled in car number 1313 of the Boston and Maine. On reaching the manager, without realizing the train of hoodoos that he was continuing, purchased a dozen hockey sticks, plus one for goal tender, making a total of 13. When the men sat down to dinner at the Copley Square Hotel. they numbered just 13, and when the waiter came to serve them, a shout of dismay arose upon the observation that his shield bore the mystic device, "13." Under the circumstances, the team feels no apologies are due for the unfavorable score, and that the prospects for winning a championship must necessarily be dark.
