In Chandler v. Field, 63 F.2d 13 (1st Cir. 1933), it was held that the interest of a remainderman under a will vested upon the death of the testator, in spite of the fact that the property was not to be distributed to him until the death of the life tenant, and then only upon his reaching the ages of thirty, thirty-five, and forty years, at which times distribution was to be made in three equal installments.
