648 BACTERIAL DISEASES OF PLANTS 



if you would be well-served and master of your subject. Often 

 it is some slight side remark of an author, sure to be missed by 

 the reviewer, that will prove suggestive to you and fruitful. 



Another prevalent sin is neglect to provide long papers and 

 books with a table of contents and with a suitable index. It 

 is too much for any author to expect the reader to make an index 

 to his book, unless he is a very guileless individual. My own 

 opinion is that such authors are lazy, rather than unsophisti- 

 cated. Any way, they deserve to be put into a pillory because 

 sometimes unfortunately it is necessary to use their books, and 

 to read much in order to get a little. Publishers are also to 

 blame for accepting and printing unindexed works. That a 

 second volume with a general index is contemplated is no proper 

 excuse for neglecting to index the first volume, because the second 

 volume may be long delayed or never published. I recall several 

 such cases. Ebermayer's " Physiologische Chemie der Pflan- 

 zen" is a capital example. A second flagrant example is il Les 

 Maladies microbiennes des animaux" by Nocard and Leclain- 

 che (2 Vols., Paris, Masson et Cie., 1903). 



ON THE ETHICS OF RESEARCH 



The scientific man is under the same moral obligations as the 

 rest of the world! He cannot plead "art for art's sake" and 

 run amuck, but like the common man must be held to strict 

 account. If he does disreputable things he must expect to 

 suffer the consequences, and he will, whether he expects it or not! 

 The scientific man, of all men, ought to be the most upright, 

 truthful and truthloving, because his whole life is spent in a 

 search for the truth. If he cannot be trusted, who may be? 

 If he has not high ideals, where shall we look for them? "Buy 

 the truth and sell it not," should be his watchword. To him 

 the truth should be a breastplate and a frontlet, a javelin and a 

 strong tower. He should sacrifice to it and love and worship 

 it above all things! Therefore, when the scientific man departs 

 from just ways the scandal is peculiarly great. For this reason 

 and because the import of certain actions is not always realized 

 at the time, especially by the younger workers, it is worth while
