after making the foregoing statement of facts, delivered the opinion of the court.
The plaintiffs are engaged in the business of packing oysters in the City of Baltimore, and, during the season of 1910-11 purchased 736,000 bushels, of which 494,000 bushels were taken from the waters of the State of Maryland, 228,000 from the waters of the State of Virginia, and 14,118 from the State of New Jersey. These oysters were inspected in Baltimore by officers appointed under the provisions of the Maryland statute, which fixed, an inspection fee of one cent per bushel to be paid, one-half by the seller and one-half by the buyer. The plaintiffs having refused to pay the inspection charge, assessed against them, litigation followed. The decision was against their claim of immunity under Art.-1, §§ 8 and 10, of the Constitution. The case was then brought here on the ground that the inspection fee of one cent per bushel charge was excessive, that it interfered with interstate *503 commence and levied an unlawful impost duty upon goods shipped into Maryland from other States.
1. The Constitution prohibits a State from regulating interstate commerce, but at the same time authorizes the collection of the necessary expenses of its inspection laws with the result that interstate commerce is to that extent lawfully burdened. Inspection is intended to determine the weight, condition, quantity and quality of merchandise to be sold within or beyond the State’s borders. It is usually “accomplished by looking at or weighing or measuring the thing to be inspected,”

possible to tell exactly how much will be realized under the future operations .of any law. Beside, receipts and disbursements may so vary, from time to time that the Surplus of one year may be .needed to supply the' deficiency of another. If, therefore, the fees exceed cost by a sum not unreasonable, no question can arise as to the validity of the tax so far as the amount of the- charge is concerned. And even if it appears that the sum collected beyond-what is needed for inspection expenses, the courts do not interfere, immediately on application,'because of the presumption that the Legislature will reduce the fees to a proper sum.

3. The unreasonableness of inspection fees may appear from the language of the act, as in
Foote
v.
Clagett,
As the act itself makes a clear distinction between inspection expenses “and other expenses,” the question at once arises as to whether the State did not provide for the collection of more than was “absolutely necessary for executing its inspection laws,” thereby rendering the statute void because it included the cost of “something beyond legitimate inspection to determine quality and condition.”
Brimmer
v.
Rebman,
This objection, apparent on the face of the act, was sought to be answered by the suggestion that § 69, which levied the tax, was but “a part of an elaborate system of inspection running through the whole law, the enforcement of which was an inseparable part of the duty of the State Fishery Force,” and that “the expense of such inspection is a component part of all the expenses of that force.”
3. But the commingling of these, various duties, paid for out of a fund raised for. inspection, does not necessarily show that the fee is excessive. For the presumption of invalidity arising from such intermingling might be met by carrying the burden of showing that, while the statute required payment out of such joint fund, the collections were not sufficient, but only helped, to pay the definitely ascertained expenses of inspection. The question of reasonableness, therefore, may be considered in the light of the practical operation of the law with a view of determining, with reasonable certainty, the .permanent relation between the amount collected and the cost of inspecting.

Maryland,
4. The Maryland statute provided for that kind of inspection that could be performed by 'looking at or measuring the thing to be inspected’ (107 XL S. 62). It fixed the amount of salary to be paid the inspectors for such services, so that the cost was definitely known. The receipts, too, are reasonably certain in view of collections in the past.
The present statute is a reenactment of an old lav/ levying the same charge of one cent per bushel. Under the operations of that law it appeared that about 4,000,000 bushels were inspected each year, producing a revenue of $40,000, one-third of which was sufficient to pay the salaries of the inspectors, the other two-thirds being appropriated to the ''other expenses of the Fishery Force.” The Comptroller in his Annual Reports called the attention of the legislature to the fact that, as required, this “excess” had been credited to the Oyster Fund. This fund was to be used — not for inspection purposes — but for “maintaining sufficient and proper police regulations for the protection of fish and oysters in Maryland waters and in the payment of the officers and men and keeping in repair and supplying the necessary means of sailing the boats and vessels of the State Fishery Force.”
Even during the year following the enactment of the new statute and the failure of many to pay,, pending the decision as to the validity of the tax, the collections were in excess of the cost of inspection. In the light of the operation of the previous act and the failure to show that the amount collected under the new, would not be more than was necessary for the expenses of inspection proper, *508 the present statute must be held to be void. The excess collected may have been valid as a tax on property in Maryland, but was a burden on interstate commerce when levied upon oysters coming from other States. This fact renders the whole tax void, because there is no claim that the intrastate commerce can be separated from the interstate shipments; or that the legislature would have taxed one and left the other untaxed.
Judgment reversed and the case remanded for further proceedings not inconsistent with this opinion.
