December 5th, 1885, about 6,500 eggs of Lochleven trout 
were milted from a Windermere char which had been kept 
waiting too long, for although the impregnation was considered 
good, there was a deficiency of milt; in 84 days about 30 
hatched ; and on July 30th, 20 were moved to pond 4. December 
17th 19 remained, and were shifted to pond 23. They were 
fully as large as yearlings of the true Lochlevens, and much 
more silvery. May 30th, 1887, moved to pond 32. Of course 
they are too young at present to show whether the cross will be 
a fertile one, but it proves that the British char, similar to the 
American, can cross with the Lochleven trout. 
It was also proposed to intercross the American with the 
British char, and on November 15th, 1882, about 9,000 ova of 
S. fontinalis were fertilized with the milt of a Scotch char, 
which had been obtained from Loch Rannoch. They hatched 
on February 9th, or in 86 days. On March 13th, 1884, 91 
lively young fish were transferred to plank pond No. 4 at 
Howietoun, and on November 12th, 1884, this pond (pond No. 4 
at Howietoun) was again examined, and 91 fish were present: 
the largest fish was 84 inches long: most of the females were 
not quite ready for breeding, as December set in they began to 
be languid ; and one or two having died they were shifted into 
pond No. 5 on December 24th, when 74 fish were transferred. 
The next day 15 died, and two on the 26th. Subsequently few 
succumbed. These fish seem, in their shallow pond, to have 
felt atmospheric changes very severely, requiring deeper water 
into which to descend. On November 25th, 1885, the largest 
was 104 inches in length, many were found to be ready to 
spawn, some not quite so, but from 35 fish from 10 to 12,000 
eggs were obtained. Some were crossed among themselves, as 
will be detailed. There were not so many males with ripe milt 
as there were females with ripe ova. This experiment has been 
repeated more than once, and with the same results, showing 
that American and British char can be interbred, and a race of 
hybrids, called struans at Howietoun, be produced. 
I now come more especially to treat of the breeding of 
hybrids, of the fertility of hybrids, I have previously shown
