of the principal species of birds in 1911, as recorded by Forbes ^ and 

 tentatively attributed to a possible seismic disturbance of unusual 

 severity. From his fm-ther remarks it may be inferred ihu I the 

 birds returned in full numbers before his observations on the coast 

 were concluded. 



I would not conclude these remarks without adding the hopeful 

 note that under the vigorous protection which Peru must sooner or 

 later extend to its sea birds in defense of its guano and agricultural 

 industries, an opportunity will be given to all the useful species to 

 regain as best they can, the condition of abundance determined by 

 the conditions of their natural environment.
