JURISDICTION TO TAX 603: sure, to tax the stock, and this right is not conditioned upon a rigidly accurate valuation; ^' nor would the fact that a certain portion of the capital stock was used outside the state affect the power of the state of charter to tax.^° In the case of an interstate railroad, however, each charter state should tax that part of the capital stock only which is proportional to the length of line within the state.^^ As has been seen, a debt has, properly speaking, no real situs; least of all is it situated with the debtor. To tax the debtor on the debt is taxing a vacuum. The debtor must of course pay a tax upon the borrowed money, or that which represents it in his hands; to tax him again upon the debt is either taxing the same property twice, or taxing a nonexistent thing.^^ In a few au- thorities this principle has been ignored, ^^ notably in a decision of Mr. Justice Holmes in the Supreme Court of the United States.^* This was an inheritance tax upon the property of an Illinois decedent; the bulk of the property involved was a deposit in a New York bank, the small remainder a debt due the deceased from a New York debtor. The court held that the inheritance of these debts was taxable in New York "not because of any theo- retical speculation concerning the whereabouts of the debt, but because of the practical fact of its power over the person of the debtor"; the analogy of the garnishment case of Chicago, Rock Island, 6* Pacific Ry. v. Sturm ^^ was cited. Mr. Justice Holmes continued : "What gives the debt validity? Nothing but the fact that the law of the place where the debtor is will make him pay. It does not matter " Welch V.
