CONCLUDING CHAPTER. 25 I 



in a year become two thousand pounds, and the feed 

 in the mean time will not cost over one hundred and 

 fifty dollars. That is to say, the increase will cost you 

 not over fifteen cents a pound. 



When these various sources of income are taken 

 into account, in connection with the wide margins for 

 profit, it is obvious that successful operations cannot 

 but pay well. I would say, however, in conclusion, 

 that I do not wish to hold out false inducements to 

 persons to go into the business with the hope of mak- 

 ing great fortunes. The item of risk is a very serious 

 one yet, and small operators cannot expect to make 

 more than a fair living. With many it will not pay at 

 all, while it is reserved only for the very successful, 

 and for those who have the few great water facilities 

 of the country, to make the great fortunes.
