‘KLONDIKE AND YUKON GOLDFIELD—CADELL. 881 
The gold production from 1898 to 1913 was as follows. The first 
column is in dollars and the second is the approximate value in 
pounds sterling, reckoning £1 as roughly equal to $5. The years in 
question end March 31.

The largest year’s output was in 1900, and was estimated at 
$22,275,000 (£4,455,000), and the total output of the territory since 
the discovery of gold is estimated at over $150,000,000 (£30,000,000). 
These figures, which show the rapid rise and steady decline of the 
production and the slow increase since 1908 after hydraulicking and 
dredging operations began, may be made more impressive by refer- 
ence to figure 5. 
The important question may now be asked: How long is the field 
likely to remain productive? This aspect of the subject has been 
discussed by Mr. McConnell in a report published by the Geological 
Survey in 1907. The total volume of the remaining river and terrace 
gravel beds was measured and the deposits were carefully sampled in 
sections. Mr. McConnell’s conclusion at that time was that after 
1906 the total value of the gold in the Bonanza and Klondike valleys 
and their tributary creeks was $53,642,620. Since then the value of 
gold obtained up till the spring of 1913 was $27,984,750, so that of 
the amount estimated there remained of gold values after 1913 only 
$25,657,800 still to be produced. 
The production in 1913, as shown above, was a little over 
$5,000,000, and since then the large dredger of the Boyle Concessions 
has added to the productive capacity of the plant. If Mr. McConnell 
is right in his figures and no fresh discovery is made, the field at this 
rate will be quite exhausted in five years’ time. But Mr. Boyle has 
carefully sampled the river gravels at the mouth of the Klondike by 
boring, and there is evidence that the capacity of the field is consid- 
erably greater than Mr. McConnell anticipated. Of course, the life 
of the field will be shortened in proportion to the rate at which it is 
being exhausted, and when all the alluvial gold is extracted the main 
hope for Dawson City will be the discovery of reefs or bodies of pay- 
able ore in the bedrock.
