All my experimental work was carried for- 

 ward with a clear recognition of that principle. 



As to the work with the raspberries, my first 

 aim was to accumulate as much available mate- 

 rial as possible. 



This has been my custom throughout. The 

 chances of obtaining results from a large num- 

 ber of experiments are proportionately greater 

 as the number increases, and I find, within limits 

 of time, that it is just as simple to conduct a 

 thousand or ten thousand experiments, or even 

 a hundred thousand experiments, as to conduct 

 a few. 



So I worked on a comprehensive scale with 

 the raspberries from the outset; and it was not 

 long before several varieties of value were devel- 

 oped; varieties, in fact, superior in size, quality, 

 and productiveness to any raspberries hitherto 

 known. 



FIRST FRUITS OF THE EXPERIMENTS 



The first of my new raspberries offered to the 

 public was named the Eureka. 



This raspberry, introduced in 1893, was de- 

 scribed as "larger than any raspberry in cultiva- 

 tion; bright red, firm, very productive, and sim-

 It is nearly twice as large as Shaffer's Colossal,
