substance found in the tuberculous blood is identical with the 

 yeast germ, nor is it clear that the substance, although an ac- 

 companiment of tuberculous blood, is really a cause of the dis- 

 ease. As to the effect of ensilage, it is well known that tubercu- 

 losis has existed where silos were unkown. However, the theory 

 is enough like the investigations of certain French scientists to 

 be of considerable interest. Under the name of mycodermin, a 

 substance derived from the culture of the yeast plant, has been 

 advocated by eminent scientists of Paris as a cure for tubercu- 

 losis and remarkable success has been claimed. It is possible 

 that with the American and French investigation combined we 

 may yet be given a new and better theory, test and cure of this diffi- 

 cult disease. The fact of immediate concern, however, is the al- 

 legded new test which laN^s claim to certain merits not posessed 

 by the test now in use.

This is a clean, interesting story of a boy who under the con- 

 trol of a rich, fussy and stingy old grandmother, grew up with- 

 out religious or distinctly elevating influences but who develop- 

 ed much sense and goodneps of character. How he came to be 

 a noble young man in the midst of untoward circumstances is 

 well portrayed, but what were the causes, of his virtues do not 

 appear to the casual reader. 



The purpose of the book seems to have been to afford the means 

 of whilingaway an evening (as we have done) in pleasant relaxa- 

 tion. There are no startling situations, no very improbable in- 

 cidents, verv few lov^e episodes, no plainly moral teachings, no 

 immoral nor questionable recitals, no allusions to religion of any 

 kind direct or indirect. 



It is a book for boys of average make-up, not those who crave 

 blood-thirsty recitals, nor who read Sunday School books,but for 

 boys, just boys. Incidentally, it is for all of us who like boys; 

 not bad boys, not boys too good to live, but boys, frank, noble, 

 generous boys, modest boys that are not too modest' peaceable 

 boys, who nevertheless will fight when honor so demands, — in 

 short boys of sense.
