SUPPLEMENTARY PAPERS. 



PKEPAEED EXPRESSLY FOR THE VOLUME OF 1S77. 



Immediately after the Juue meeting at Soutli Haven, several parties -were 

 addressed for papers to place in the annual report of the society. It was thought 

 desirable that in the pajDers thus prepared there should he a balance main- 

 tained between science and its application, and those who read can best judge 

 of the success of the effort. 



The article by Islv. Ilalsted is a carefully prepared paper upon a topic which 

 comes home to the grape growers of Michigan, and will be valuable as giving 

 accurate statements regarding the growth and propagation of the parasitic 

 plant, that is such an enemy to tlie vineyard. To joroperly defend ourselves 

 against enemies we need to know their habits, strength and methods of war- 

 fare, and in this paper Mr. Halsted has given us just this kind of knowledge 

 — the result of long and careful examination of the grape mildew. 



The article by M. B. "Williams of Saugatuck, on " Growing Peaches for 

 Market," is the carefully prepared opinion of an orchardist whose experience 

 in the growing of peaches has been large, and who speaks from no theories, but 

 gives the result of his long practice. 



Professor Prescott's paper upon " The Chemistry of Fruit Kipening" is full 

 of suggestions that are invaluable to the practical fruit grower, and the read- 

 ers of this volume will long have reason for gratitude toward the author of this 

 article so kindly furnished them. 



Prof. Prentiss' address gives just the estimate of the education acquired at 

 our Agricultural Colleges that we all need to carefully weigh, and we wish to 

 call especial attention to his estimate of that knowledge which gives appre- 

 ciation of the beautiful things in nature and in art, and which gives to life 

 that satisfaction which cannot be bought Avith money nor lost with age. 



The concluding article by the Secretary simply records the results of a few 

 years of experience combined with some explanation of the reasons for success 

 in the most approved methods of transplanting.
