100 FEDBBAL BEPORTEB. �"If any person, ♦ * liable to pay a tax, shall neglect or refuse to pay the same after demand, the amount shall be a lien in favor of the United States fram the time it was due until paid, * * * upon all property, etc., belonging to such person," etc. The statute does not say "upon all prop- erty which may have belonged to such person when the tax accrued." �This or similar language would, I think, have been em- ployed if congress had intended to give the statute this effect.

The gov- ernment may protect itself by diligence if the view I take of the statute shall prevail; but, if the opposite vifw is sus- ��� �
