Prof. Sanderson : Northeastward, yes sir. The 

 brown tail extends practically through eastern Massachu- 

 setts and New Hampshire, and up into Maine, I think as 

 far as Waterville. It has extended more -particularly up 

 the coast. That is about its northern limit. The gypsy 

 moth covers pretty nearly the same territory at the pres- 

 ent time. I do not know that either of them are found 

 in Vermont. 



Question : Have you had any trouble with arsenate 

 of lead or Bordeaux mixture injuring the fruit? 



Prof. Sanderson : I think not. We have found that 

 the amount of spray deposited upon the fruit is not in- 

 jurious. If it gets a little to thick, it is an easy matter 

 to rub it off in packing. Of course, if you are using the 

 spray right there is no necessity of having it on too thick. 

 In some cases where I have known parties to spray for 

 the gypsy moth, they have got on too much. 



Mr. Platt : Do you know of any control for the 

 Baldwin spot — what we know as the Baldwin spot? 



Prof. Sanderson : That depends on what you are 

 talking about. There are two or three different things 

 that have been confused under the name of "spot." Our 

 botanist, Mr. Brooks, has done considerable work on a 

 disease which he calls the "fruit spot," and which some- 

 times has been called the Baldwin spot, and which appears 

 on the apples as a little greenish or brownish spot about 

 the time it is ripening, and becomes black on others, or of 

 a blackish color. It is due, as I understand it, to a fun- 

 gus which can be controlled by spraying with Bordeaux. 



There is another disease to which my attention was 

 called this morning, in which the color of the spots is 

 greenish. Here is a specimen. So far, he has been unable 

 to isolate any fungus from it. He is investigating with 

 the idea of trying to determine what the cause of it is. 

 Some botanists have claimed that they could not control 

 it. With any of these sprays, and none of the sprays that
