5. — THE HATCHING-APPAKATUS. 



The water-supply. — In the season of 1872, I used water for hatching 

 from a spring-brook which emptied into the McCloud a short distance 

 above the site of our present camp, and which had its sources about a 

 mile to the west of the river. This brook gave us no end of trouble on 

 accountof its unsuitableness to its purpose. Its average ilowiu the morn- 

 ing was a little over 1,000 gallons an hour, but at night, after a very hot 

 day, it would shrink to 250 gallons. It would also heat up some days to a 

 very dangerous temperature ; then, again, the hogs, which run in the woods 

 in a semi-wild state, would wallow in it and make it so roily that all 

 attempts to filter it clean were fruitless ; and, last but not least, there 

 was present in the water all the time a vegetable growth, resembling 

 our eastern Conferva, yet somewhat dissimilar to it, that no device of 

 ours could cleanse the water of. It seemed to be ubiquitous, and gave 

 a great deal of trouble. 



These combined disadvantages of the water-supply of 1872 decided 

 me to abandon it this season, and to look elsewhere for water. But here 

 a new difficulty arose. There was no other spring or brook of any mag- 

 nitude within several miles. To go that distance to locate would either
