unwarranted, and upon recommendation of that Bureau in August it 
was condemned and dismantled. 
On May 21 the Crane struck a rock in Grenville Channel, which 
damaged the keel so that it was necessary to have the vessel hauled 
out for a few days on the marine ways at Ketchikan for repairs. 
AERIAL PATROL 
The use of airplanes to supplement the vessel patrol of traps and 
fishing grounds for the protection of the Alaska fisheries, although 
limited by available resources and at times by unfavorable weather 
conditions, is of distinct advantage in the conservation work and should 
be greatly expanded. The speed with which distances may be covered 
along the indented coast line makes this type of patrol highly effective 
in deterring as well as in apprehending violators. 
Chartered airplane service for the “patrol of the fisheries in 1939 
oe furnished by 6 companies on 31 days. The total flying time was 
4% hours, during which the planes traveled 6,859 miles. This patrol 
GER 2 trips made from Cordova i in which evidence for convictions 
in 6 violations was obtained. One trip was made in the Cook Inlet 
area covering the east side of the Inlet from Anchorage to Kenai and 
the west side on the return to Anchorage. In southeast Alaska, from 
6 to 11 hours flying time was used in each of the Juneau, Ketchikan, 
Wrangell, and west coast of Prince of Wales Island districts. 
In addition, chartered airplane service was used for survey and 
photographic work in connection with scientific investigations of the 
salmon in the Bristol Bay region from May to October. Transpor- 
tation was provided on 67 days during this period, the total flying 
time was 206 hours, and the distance covered was 20,645 miles. Con- 
siderable patrolling was done by aircraft in the Bristol Bay area, thus 
compensating, in part at least, for the lack of adequate patrol boats. 
COMPLAINTS AND PROSECUTIONS 
In 1939, 57 cases of violation of the Alaska fishery laws and regu- 
lations were referred to representatives of the Department of Justice 
for prosecution. Six traps, 22 seine boats, 24 gill nets, and 5 trolling 
boats were involved in these violations. 
Two cases were tried in the District courts, one at Juneau by jury, 
and one at Ketchikan by the court. In each of these cases the defend- 
ants were found guilty and were given substantial fines. All the other 
cases were tried in the U. S. Commissioner’s court. Of these, the 
defendants in 42 cases pleaded guiliy to the charges preferred against 
them and were fined. In addition, the salmon in their possession at 
the time they were apprehended were seized and sold for the account 
of the Government. In 6 cases the defendants were given suspended 
sentences, and in 2 cases they demanded trial by jury and were found 
not guilty. Five cases were dismissed. 
In addition to the above, 4 gill nets and 1 purse seine that were being 
used in violation of the fishery laws and regulations were seized, the 
owners of which were not apprehended. The fish in the nets were 
released or sold and the gear was confiscated. 
The following schedule lists the violations, by districts, and includes 
the penalties imposed.
