TRANSFERENCE OF BLACK BASS. 155 



the cans was kept at about 21° until within two days of Manila, when 

 it was increased gradually to 23°. Wlaen we' arrived in Manila the 

 temperature of the water in the cans was 23°, that of the air was 29°, 

 and of the sea water 28°. 



The fish had to be transported from Manila to Dagupan by rail, a 

 distance of 193 kilometers, and thence 120 kilometers overland to 

 Baguio, a mountain town in the Province of Benguet. This was the 

 most difficult part of the trip, but it was accomplished in two days, 

 with the loss of but one fish. The temperature of the water was lowered 

 considerably during the last stages of the trip to Baguio, at which 

 place the fish were planted in three distinct spots : One lot in the small 

 lake near the Hotel Pines, another iit a deep pool in the Trinidad Eiver, 

 and a third in the large Trinidad Lake. (See diagram, fig. No. 2.) 



In December, 1909, I visited the places where these fish had been 

 planted, and found that those placed in the small lake near the Hotel 

 Pines had escaped early in the year; nothing was seen or heard of those 

 planted in Trinidad Kiver, but a tale was current of the capture of 

 some large fish by the natives. The bass planted iu Trinidad Lake 

 had flourished and multiplied exceedingly well. A short trial with a 

 fly gave sufficient j^roof that the lake was well stocked, as not only one 

 of the original fish, but also one of the offspring was hooked; the latter 

 (see Plate I) was 190 millimeters long and the parent fish was almost 

 twice this length. 



During February of the past year the small artificial lake in front 

 of the Hotel Pines at Baguio was transformed into a good spawning 

 pond by raising its walls, putting in concrete gates, and adding several 

 loads of gravel for spawning beds. Twelve large bass caught in Tri- 

 nidad Lake with a fly hook were transferred to this breeding pond on 

 February 23. By May 4 they had spawned and there were hundreds 

 of young bass in the pond, many of these have since been planted in 

 other places, and some large bass were placed in Cayman Lake at Los 

 Baiios, Laguna Province. It is now an assured fact that people who live 

 far inland may have this most desirable addition to their diet, and for 

 those who care for it there is the pleasure and excitement of angling for 

 this noble game fish. 



TEANSFEKRING MOSQUITO-EATING FISH. 



In the year 1905 I was authorized by the Government of the Hawaiian 

 Islands to secure and bring to Honolulu a shipment of live top minnows, 

 Fundulus heteroditus (Linn.), Gambusia affinis (B. & G.) and Mallienesia 

 latipinna La S. to assist in ridding that place of the pest of mosquitoes. 

 These fishes belong to the family Poeciliidce and axe found in the southern 

 United States. They feed almost exclusively on the eggs and young of 

 the mosquito. Fifteen hundred dollars United States currency was
