Tarpon I'^ishing in Mexico. t,^^ 



February, 1905, 1S7 tarpon were cauj^ht. 

 March ,, 229 ,, ,, ,, 



April „ 169 ,, 



May ,. 72 ,, 



These fiti^ures would of course vary largely with the number 

 of the guests staying- at the hotel, and so cannot be taken to 

 represent the proportion of tarpon in the river during the different 

 months. 



There have not been any cases of yellow fever at Tampico for 

 three c^r four years, and the sanitary improvements make an 

 outbreak less likely as time goes on. 



The Sfes;-oj)iya fasciata, commonly called oul there the 

 zebra mosquito, is the only agent by which infection is carried. 

 This mosquito is easily recognised by the white stripes longi- 

 tudinallv traversing: the thorax, the white bands round the 

 abdomen and the lower half of the legs. Me is too seriously 

 handicapped as he only bites in the day, and in order to 

 impregnate a human being widi the yellow fever bacillus, he 

 must have bitten a person suffering from the disease at an early 

 stage. Hence no mosquitoes, no danger of yellow fever, and no 

 ye'llow fever patients, harmless indigenous mosquitoes. 



Durincr mv stav 1 did not come across any of these 

 customers, and they are by no means common. I do not attempt 

 to deny the presence of the anopheles mosquito, the carrier of 

 the malarial parasite. This fellow cannot be trusted to refrain 

 fiom biting by day or night : but it is only a very dissipated 

 anopheles that bites in the middle of the day. They too must 

 have bitten an infected person before they can become infected
