248 ANNUAL KEPORT. 



wares, Concords, lonas and Janesvilles. They were the finest I 

 ever saw anywhere. 



Gen. W. Gr. Le Due. On which side of the lake is this vineyard ? 



Mr. Pearce. The east side sloping to the west, and the rows all 

 east and west. 



Gen. Le Due. How wide is the lake opposite the vineyard? 



Mr. Pearce. About four miles ; timber land east and back of 

 the vineyard. 



Gen. Le Due. You can feel the descent of moisture inland, 

 four to fifteen miles, sometimes fifty. 



Col. Stevens thought the influence of moisture was overrated. 

 Where is the water in Scott county? What water is near Mr. 

 Grimes? 



Mr. Pearce. The best grapes in the state are always to be 

 found near bodies of water, either on our lakes or rivers. You 

 will find this true every time. 



Mr. Plumb. Water does it. For every mile of difference in 

 distance from water, you may reckon ten degrees in temperature. 

 This has been tested and proved. Ten degrees higher in day time, 

 ten lower at night. This makes all the difference between success 

 and failure in many seasons. The equalization in temperature is 

 what is needed. Deep cultivation might remedy the defect of 

 location in part, but not fully. 



Gen. Le Due. Would any of you advise the planting of a vine- 

 yard on a steep northeast slope near a stream of water, limestone 

 soil, previously timbered? 



Mr. Golden instanced a vineyard so situated that was successful. 



Mr. Gideon. The most unnatural exposure for grapes. 



Mr. Harris has seen many wild grape vines on northeast slopes, 

 but does not know that they bear. 



Prof. Porter. Experience is against a northeast exposure, but if 

 I had no other, I would plant there. 



The Secretary. In connection with this discussion, I will print 

 here the report of Mr. Ludluff.
