LETTERS TO MR. GIBB 



[CHAP. xv. 



I hope you are having good harvest weather, but indeed 

 this is the first really good bright summer's day we have 

 had for a long time, and to my eye the wheat round here 

 has a grey look instead of the bright colour. 



August 28, 1894. 



Your packet of infested straw came safely to hand this 

 morning and I am very much obliged to you for kindly taking 

 all this trouble. I have repacked the Hessian fly straws,

winding a thread over the place of deposit of the puparia on 

 the barley straw for fear they should get from under the 

 sheathing leaf and be lost. I am sure Dr. Ritzema Bos will 

 be very grateful for the help, and also for its coming so 

 promptly. 



Thank you also for the Chlorops (Gout fly) specimens ; 

 they were particularly acceptable just now, for, if all is well, 

 Professor Riley means to look in early next week before he 

 returns to the U.S.A., and I think he would like to see them.
