trarily determined by the association. The constitution provided for the appointment of ah executive ■ committee, whose duty it was to examine all applications .for membership in and to report on the same to the association, after which it was to decide whéther the applicants should be admitted or not. If they were not acceptable the applicants would not be admitted, and whether they were or not, was a matter for the. arbitrary .decision of the association. Its- decision that they wefe not acceptable, was sufficient to bar their entrance.
Again, it appears that plaintiffs were not eligible under the constitution, because’ they-did not always carry stock worth $3,000, which by section 1 of article Ij was made a condition of eligibility to membership. True, it was stated in evidence that this provision had not been enforced, but there was no averment Or proof that it had been repealed, and there was nothing to prevent its enforcement'-at any time that an application was máde by any one who would not come up to the condition. The case stands, therefore, that the plaintiffs had not been asked to join the association at its formation; that they did not fill, the condition provided for in its constitution .as to eligibility, and that if they' had applied their application was subject to arbitrary, rejection.
The plaintiffs, however, could not, by virtue of any agreement contained in such association, be legally put under obligation to become members in order to enable them to transact their business as they -had theretofore done, and to purchase tiles as they had been accustomed to do before the association was formed.
The. consequencés of non-membership were grave, if not disastrous, to the plaintiffs. It has already been shown how the prices of tiles were enhanced so far as plaintiffs were concerned, and how by means of this combination interstate commerce was affected.
The purchase and sale of tiles between the manufacturers' in one State and dealers therein in California was interstate commerce within the Addyston Pipe case, 175 U. S. 211. It was not a combination or monopoly among manufacturers simply, ■but one between them and dealers in the manufactured article,
