SECRETARY'S REPORT. IQl 



repeated, protracted, and carefully conducted experiments, ■weighing 

 the food daily, and weighing the animals fed at proper intervals. 



The indications of analysis would hardly lead us to anticipate 

 finding fifty, or even seventy-five bushels a fair equivalent of a ton 

 of good, well cured herds grass or clover; yet in connection with 

 what we know of the expense attending their culture, the amount 

 wo can grow, and the subsequent condition of the land where a good 

 crop has grown, they do lead us to anticipate a greater amount of 

 food, and cheaper, than Ave can otherwise obtain, and better crops in 

 after years.
