WARSAW IIORTICULTURAI. SOCIETY, 365 



One fact or one expoviinent flo(>s not establish a theory, but I 

 infer from the facts above stated that this insect breeds very ra}>idly 

 in the peach and phim. and when these fruits fail attack the apple, 

 feedin<i: njion it. as well as de})<)siting their eg|:;s in it. This is }iro- 

 bably one of tlie ])rinci])al causes of "scab," which some seasons 

 d«'stroys a large portion of our a]tples: and in my opinion the sooner 

 the ap]>le-<i:rower l)anishes every peach and plum tree from liis 

 orchard the better it will be for his pocket. 



J. T. Johnson endorsed the re])ort. 



C. N. Dennis and J)r. N. Lyon })laced on the table tine and per- 

 fect s})ecimens of apples and iG^rapes, and Dr. Lyon recommended the 

 introduction, as far as possible, of new varieties of fruit, free from 

 all hereditary taint. He said the incipient cause of disease is often 

 found in the original tree and is transmitted by grafting, and tli;it 

 our potatoes, berries, etc., are all sul)ject to the same trouble. 



Mr. Berry said it is the business of our Society to discover the 

 causes of thesQ troubles and thus learn to npply proper remedies, and 

 wet and unfavorable weather, a want of drainage or iiuproper soil, 

 perhaps had their intiuences. 



Geo. 0. Hilton said there was very little fruit in Southeastern 

 Iowa this year. 



Vj. Stewart, said: My soil rests upon a stitf joint clay. From 

 planting I force the growth of my tree as much as possil)le until 

 time f(jr bearing, and when I want fruit I cease to cultivate. To 

 prevent sod from forming T mulch heavily, and let the weeds take 

 care of themselves. I have had ;i constant crop of aj)j>les for fifteen 

 consecutive years. The speaker insisted that some or(diardists 

 destroyed the fibrous roots by too close plowing, and that they were 

 the mouths or feeders of the tree. 



J. C. Berry did not think our orchards were to become a failure. 

 Wheat grows well in Dakota because of the abundance of alkali in 

 the soil. On our new prairies a quarter of a century ago \vr had 

 large crops of wheat. J*erha})s it was owing to the accumuhition of 

 alkali from the ]irairie tires. 



In answer to the question, ** Is it a good time now to transphmt 

 tlu' strawberry?" Mr. II. D. Hrowu saiil. " ^'es. it' moist weather 

 prevails.""
