growers in any locality infested would omit using any patent 

 tree protector ^ tar or any other preparation, they would find that 

 in two or three years the canker worms would disappear from 

 starvation, or lack of sufficient food, of a proper kind, to bring 

 them to perfection, sufficient to propagate their kind for another 

 year's operations. 



I have come to this conclusion after careful observation and 

 my own practice ever since the appearance of canker worms in 

 my locality. A majority of my neighbors have used every 

 known remedy to save their apple crop^ but have met with very 

 poor success, while those who have adopted the " let alone

In short, I consider all of the so-called tree protectors, tar, 

 printers' ink, etc., (except for puffing a worthless article,) so 

 much money and time thrown away. 



Respectfully submitted,

 When the canker worms in small numbers first made their 

 appearance in my orchard, as many as eight years ago, I 

 thought I would pay no attention to them. But as they 

 increased very fast each year, I found I must do something, or 

 my trees would be entirely destroyed. I commenced experi- 

 menting in 1870, by putting tarred paper and printers' ink on 

 about one acre, or nearly one hundred trees, and the same 

 numl)er with paper and tar. I also put Ordway's Protector on 

 forty or fifty trees. The Ordway Protector protects them from 

 the grub, but not from the worm, as I found in the last days of 

 April the worms were ascending the trees over the Protector. 

 I placed paper and tar above the Protectors, and caught thous- 

 ands before the middle of June, when every leaf was eaten. 

 The ink was too expensive, as it was necessary to apply it 

 every day, or at least every other day. I tried about one 

 hundred trees with boxes, to which was attached a gutter filled
