“ It is not necessary that the defendant should controvert or dispute the claim. It is sufficient that he does not satisfy it. It might be that he could not truthfully dispute it, and yet, if from inability, or, mayhap, from indisposition, he fails to satisfy it, it cannot be that because the claim is not controverted the Federal court has no jurisdiction of an action brought to enforce it. Jurisdiction does not depend upon the fact that the defendant denies the existence of the claim made, or its amount or validity. ”

“ The appointment of a receiver in the case of a railroad engaged in interstate commerce does not necessarily involve any such controversy. Jurisdiction to appoint a receiver by a circuit court of the United States in cases of railroads engaged in interstate commerce has existed by reason of diversity of citizenship in the various cases between the parties to the litigation, and not because the railroads were engaged in interstate commerce. The necessary diversity of citizenship is alleged to exist in the case before the circuit court, and there is no suspicion as to the truth of the averment. ”

“ A refusal to appoint a receiver would have led in this instance almost inevitably to a very large and useless sacrifice in value of a great property, operated as one system through the various streets of a populous city, and such a refusal would also have led to endless confusion among the various creditors in their efforts to enforce their claims, and to very great inconvenience to the many thousands of people who necessarily use the road every day of their lives. ”
