while the other 50 per cent were taken from the stock fish 

 at the station. In May while fishing was in progress in the 

 Rio Nirihuah for trout from which to collect eggs, one 

 brook trout was caught measuring 48 centimeters in length, 

 and weighing probably about two kilos or more. This fish 

 was full of eggs. The same day a female landlocked 

 salmon, measuring 43 centimeters was taken, but she had 

 already deposited her eggs. A great many very fine trout 

 and landlocked salmon have been taken at various times 

 from the Rio Nirihuah. 



We continue to receive reports which indicate the complete 

 success resulting from the developed pejerrey eggs planted 

 in various waters of the republic where no pejerrey existed. 

 Some time ago, in January of this year, I believe, Mr. 

 Schultz, of the Officina Meteorologica, told me that it was 

 found necessary to remove the water from the small pond 

 at their magnetic observatory at Pilar, and that when the 

 pond was almost dry several specimens of pejerrey 15 to 20 

 centimeters in length were captured. These were the result 

 of a small number of eggs planted in this pond in October 

 or November of 1907. Early in May of this year I was told 

 by Mr. M. G. Fortune, of San Martin 195, that he had been 

 recently informed by Mr. David Ripley, of Buena Esper- 

 anza, that he (Mr. Ripley) had seen hundreds of pejerrey 

 from 1 5 to 25 centimeters long in the laguna on his estancia, 

 where he had planted a small number of pejerrey eggs fur- 

 nished to him by this section, in October, 1907. Under 

 date of November 20, 1908, Mr. Edmundo Wernicke, of 

 the estancia "Don Roberto," Mercedes, Province of San 

 Luis, wrote me that he had stocked many lakes in that 

 province with pejerrey by taking the fish from his lakes in 

 which I planted developed eggs in November, 1904. I quote 

 the following from his letter: "When you return to your 

 country you may be sure you leave many friends in the 

 Province of San Luis who have never met you, but who 

 know you through your work of having introduced the 

 pejerrey into this section of the country. The people of the
