Or of many others. But it certainly does if the man who has agreed to deliver the labor of a thousand coolies or a thousand Japanese could not have any remedy against the man whose contract is to be delivered. The latter man is left free forever. and the other man. of course. can not have a remedy. There can not be a remedy for a specific performance against him that would be of any value. and there could not be before. There is no reason why he should not be liable in damages if he has made an imprudent contract of that kind which the man whom he undertakes to act for can not execute.
