Prof. Burrill — When the berry is abgut half grown a brown 

 spot appears, and spreads rapidly. Soon the berry shrivels and sticks 

 to the vine. The spores remain on the shriveled fruit all winter, and 

 in the spring will take effect on the young fruit. I have seen vine- 

 yards that have never been affected, the rot producing influence not 

 having reached them. 



E. A. Riehl — The rot T referred to is what the Professor calls 

 the brown rot. If these spores have moisture enough they germin- 

 ate, otherwise they die. Hence the prevalence of rot in wet weather. 

 Where the shape of the ground will permit I prefer to have my 

 vineyard rows run north and south. The idea that Norton and Cyn- 

 thiana do not rot is a mistaken one. I have had thirty years expe- 

 rience with grape-growing and know whereof I speak. 



President Galusha — Are grapes less liable to rot on sandy than 

 on clay soils? 



S. M. Slade — I have a vineyard on sandy soil that has suffered 

 little from winter-killing or rot. I know of a vineyard trained on a 

 single wire that has produced very fine grapes. This plan gives a 

 free circulation of air, permits the sun to dry the leaves early in the 

 morning, and gives the fruit the necessary shade. 



Prof. Burrill — Has any one present tried the experiment of 

 drawing paper bags over the bunches ? I think it can be made profi- 

 table. 



Parker P]arle- — I wish to emphasize the remarks of Prof. Bur- 

 rill in relation to bagging. It protects from rot, birds, and insects. 

 It costs about half a cent a pound, but increases the market value of 

 the fruit many times that amount. The bag must be put on while 

 the grapes are very young — as soon as there is anything to tie to. 



.T. B. Miller — I came hereto learn. One tells us to train low, 

 another to put the vines up several feet; which is right. I have two 

 vines that are trained long, and run twenty feet, that are doing bet- 

 ter than any others that I have. 



Prof. Budd — The mite that works on the pear works on the 

 leaf and fruit of the Labrusca grape. What is known as rot on our 

 Iowa grapes is supposed to be the work of an insect, possibly the 

 apple curculio.
