Honey-dew is found in most countries where the soil is bar- 

 ren or the climate dry, and may be the same with the manna

 jsweet liquids ; and some of the Aphis genus are kept as milch- 

 cows by the ants, which stroke them down or tickle them witli 

 their antennae, when they want some of the sweet milk, and 

 the captive Aphis obligingly squeezes out the secretion tlirongh

Note. — Nearly all the information about the quadrupeds and birds of Cali- 

 fornia, heretofore printed, may be found in the papers of Dr. J. S. Newberry 

 and Professor S. F. Baird, in the United States Pacific Railroad Survey Ee- 

 ports. Most of my information about the fishes and fisheries, and much even 

 of the language, is derived from the conversation of Dr. W. 0. Ayres, of San 

 Francisco ; and I hope that, as he is the most competent man, he will some 

 day treat the subject in a special work.
