 not be prepared to enter upon the trial of more than ten each 

 year, if he is to do the best possible work, he will not select 

 the first ten experiments that present themselves to his mind 

 when confused by a multitude of duties, many of them but 

 slightly connected with this line of work ; but, realizing the 

 importance of the work, if his mind is not distracted by other 

 duties, he will give it his full, individual attention, until by 

 thorough investigation he feels reasonably sure that he has 

 selected the ten experiments that are the most important to 

 be tried first, though it may take months of research and 

 thought. If he does not do this, luit takes the first ten that 

 present themselves to his diversified mind, it may be fifty 

 years before he comes to the other ten experiments that 

 ought to be tried first.
