required by the War-time Profits Tax Assessment Act 1917, setting OF forth a statement of the profits of their business during the financial year ending 30th June 1916.
3. The Commissioner caused an assessment to be made thereon for the purpose of ascertaining the profits upon which war-time profits tax should be levied for the period from 1st July 1915 to 30th June 1916, and subsequently amended the same.
4. The Commissioner assessed the appellants to war-time profits tax in the sum of £1,310 17s. 8d. by the said amended assessment.
5. The Commissioner included in the said assessment certain returns from the bark of wattle trees which had been stripped by the appellants from certain lands in their possession and sold and the proceeds received, all during the said financial year ending on 30th June 1916.
6. A wattle tree must be from three to four years old before its bark is suitable for stripping, and the tree can only be stripped once inasmuch as the stripping results in the death of the tree.
7. The appellants by notice of objection objected to the said amended assessment, and claimed that the respondent had erro- neously included in the said amended assessment as part of the profits for the said period the whole of the proceeds of wattle bark stripped and sold during the said period although such proceeds included the growth of wattle bark during several years. The appellants claimed that the proceeds received upon the sale of such wattle bark should be divided by the number of years during which such bark had grown, and that the proportion of profits attributable to the accounting period should be arrived at by dividing the total amount of profits from the sale of the bark by the number of years of the growth of the bark before it was stripped.
8. The Commissioner disallowed the said objection, and the parties agreed that the said notice of objection should be, and the same was, treated as an appeal and forwarded to this Court pursuant to sec. 28 of the said Act.
9. On the hearing of the appeal before me the following questions, which in my opinion are questions of law, have arisen, which I state for the opinion of the High Court :-
