cussed. The importance in the purchase of nursery stock of 

 securing trees from localities free from this disease is urged. 



11. The occurrence of a fusariuni disease of cucumbers and 

 allied plants, the first symptom of which is wilting which usu- 

 ally results in the death of the plant is pointed out. This at 

 present affects chiefly hothouse crops, hut in some localities is 

 found in out-door crops. In the case of hothouse crops, ex- 

 cessive crowding and forcing seem to produce jilants with 

 tissues peculiarly susceptible. Growers are advised against 

 such treatment. 



12. The fact that large numl)ers of fruit trees of all kinds 

 are in unsatisfactory condition due to unfavorable climatic 

 causes, and the presence of San Jose scale is pointed out. The 

 gradual death of the feeding roots due to the excessive drought 

 and extreme cold, the presence of sun scald often followed by 

 canker are among the more important results. Methods of 

 treatment are suggested. 



13. The essential features of a satisfactory nozzle for spray- 

 ing, especially the larger trees, are described ; and briefly stated, 

 the most essential points appear to be the capacity to throw the 

 material long distances and yet to break it into a mist-like spray. 

 A nozzle believed to be a great improvement on any type pre- 

 ^ iously made is described and illustrated. 



14. The general character, digestibility and the best methods 

 of use of distillery and brewery by-products are stated, and 

 rations for difterent classes of farm animals are suggested. 



15. The composition, digestibility and feeding value of apple 

 pomace lead to the conclusion that if used in a balanced ration 

 about four pounds of the pomace will equal in value one pound 

 of good hay. 



16. The minimum digestible protein needed daily by a cow 

 weighing 1,000 pounds and yielding 20 pounds of milk is about 

 1.4 pounds; but an increase of about 35 to 50 per cent above 

 this amount seems likely to yield profitable returns. For a 

 900 pound cow giving 12 quarts of milk per day about 1.8 

 pounds of digestible protein in the feed daily should be satis- 

 factory. An increase in the protein above the minimum does 

 not appear to affect the composition of the milk.
