ON BRITISH AND FOREIGN STATISTICS OF INTERNATIONAL TRADE. 197 
colonies have attempted this in the annual report which they furnish on 
agricultural and industrial productions. It is clear, however, that great 
care must be taken in order to avoid the counting of the same wealth 
several times, owing to the different processes of manufacture which 
wealth undergoes. For the present the Committee desire, however, only 
to direct attention to the importance of this matter from an Imperial 
point of view, in the hope that at some time it may be possible to 
establish an efficient census of production, agricultural and industrial, 
within the Empire. 
(6) A common statistical year should be established. 
The Committee render cordial thanks to the Customs authorities of the 
several self-governing colonies for information which they have afforded 
in regard to methods of collecting the returns of imports and exports, 
and also to the Colonial Office for information with regard to the Crown 
Colonies. 
Age of Stone Circles.—Interim Report of the Committee, consisting of 
Mr. C. H. Reap (Chairman), Mr. H. Batrour (Secretary), Sir 
Joun Evans, Dr. J. G. Garson, Mr. A. J. Evans, Dr. R. Munro, 
Professor Boyp Dawkins, and Mr. A. L. Lewis, to conduct Kx- 
plorations with the object of ascertaining the Age of Stone Cireles. 
Tne ‘stone circle known as the ‘Stripple Stones,’ situated on Bodmin 
Moor, Cornwall, on the slopes of Hawkstor, was selected by the Com- 
mittee as a site upon which to conduct excavations this year. The 
necessary permission was kindly given by the landowner, Sir William 
Onslow, subject to the area disturbed by digging being made good. A 
very careful and systematic exploration of the circle was made in June, 
a preliminary examination having been made earlier in the year by Mr. 
Balfour and Mr. Gray. As previously at Arbor Low, the Committee 
were fortunate in securing the services of Mr. H. St. George Gray, who was 
placed in charge of the excavations, which lasted a fortnight, and which 
were very satisfactorily organised and conducted. He received much 
kind assistance from the Rev. Vernon Collins of Blisland. Some twenty 
or more trenches were dug in various directions, especially along the fosse, 
which was carefully explored, it being for the most part poorly defined on 
the surface. In spite of a very thorough search, relics were disappoint- 
ingly scarce, a few flint flakes and some wood at a low level alone being 
found. There was a total absence of metal, as was the case at Arbor 
Low. A very careful contoured survey-plan of the circle has been made 
by Mr. Gray, who has also surveyed and photographed some of the other 
circles in the neighbourhood. Owing to the late date at which the exca- 
vations were completed, the full report, which will give all details in 
regard to the work and a complete description of the circle, is not yet to 
hand, and will be presented next year. 
The Committee ask to be reappointed, with balance in hand,
