Late-type, bright giants and supergiants in southern and northern concentrations and in the general field, the ages of the stars from stellar models, and the abundances, based on intermediate band photometric indices, are investigated. It is found that the bright giants and supergiants of types F to K among association members in the concentrations and in the general field are overabundant in metals, with P(Fe/H) approximately equal to 0.25. These bright giants, and the early-type association members brighter than about M(V) = -1 mag (mode B stars), are determined to be younger than 5-6 x 10 to the 7th yr. The fainter (mode A) main-sequence members of the association are shown to be near 2 x 10 to the 8th yr with P(Fe/H) approximately equal to 0.
