you to recoguize these early stages in swift-riinuiDg streams in your neighborhood. 

 If the period during which the flies appear should be short, and if you are able to 

 keep the fowls in a dark house during this period, you will probably find it advanta- 

 geous to do so. The best applications to be made are indicated in the report, and will 

 probably prove to be fish oil or something similar. Persian insect powder puli'ed upon 

 the fowls will kill all of the gnats which happen to be on it at the time, but will 

 probably not act as a preventive. * " *. — [April 16, 1888. ] 



THE BLACK-POLLED TITMOUSE nESTROYING CANKER WORMS. 



Paleacrita vernata, or Spring Canker-worui, seems to be troubling our orchards here- 

 abouts for the first time. I notice the birds and chickens are destroying a host of 

 them. If London purple does not kill both, all will be well. One little bird, the black- 

 polled chickadee or titmouse (Pants atricapillus), isbungry for them. — [W. S. Newlon,

KEROSENE EMULSION AND THE CABBAGE MAGGOT. 



Your kerosene emulsion has done wonders on Anthomyiahrassicw. We have used it 

 on our cabbage, that was badly infested with cabbage fly, and now, upon examination, 

 they are entirely gone and the plants not hurt the least, but your formula is too 

 strong ; 9 gallons of water to 1 of kerosene has killed all the plants we put it on ; 

 after that we mixed it 1*2 gallons of water to 1 gallon of emulsion, and this has done 

 no harm to the plants, but hasdestroyed all the worms. — [Ziramer Bros., Mobile, Ala. 



AFTER EFFECT OF THE OVIPOSITION OF THE PERIODICAL CICADA. 



* * * Five or six years ago the so-called 13-year locusts did great damage to 

 our orchards. I send a cut from a twig which shows their work. The wounds are on 

 the underside of everj' branch less than an inch in diameter. Trees in such plight 

 cau not give crisp and juicy fruit. The apples are small, wilted, and tough, and let 

 go their hold on the tree with a slight breeze. My row of Rome Beauties fruited 

 heavily the past two years. At harvesting time not more than a dozen remained on 

 the trees. It was the same with other varieties. 



As far as my observation extends other orchards are like mine geatly damaged by 

 the locusts. 



This is not a flattering statement, but I thought it right to give facts, and hope to 

 be able to give a more favorable account in future. — [A. G. Alexander, Queen City, 

 Mo., February 13, 1888.

MORE TESTIMONY ON THE BUCKWHEAT REMEDY FOR CUT-WORMS. 



Have you ever noticed the effect of plowing under a crop of buckwheat to keep cut- 

 worms ofl" the land ? It has been our experience the last fifteen years that wherever 

 we turn under a crop of buckwheat we will not have any cut-worms on it ; but this 

 year has been the most remarkable of all. The seed we got from the North was of a 

 very poor quality, hardly coming up at all. So we sowed the remaining seed, about 

 two bushels, on a piece of about one-half acre. This gave ns a good stand. Now 

 everywhere ciat-worms are plenty, except on the little piece where the buckwheat has 

 been turned under. We always have been free from cut-worms on land we have 

 plowed buckwheat under, while our neighbors have sometimes their whole crop 

 ruined by them. — [Zimraer Bros., Mobile, Ala., February 6, 1888. 



AN APPLICATION FOR BUFFALO GNAT BITES, 



In looking over your report for 1886 I do not see a preventive for buffalo gnats that 

 I used successfully during the war. In the absence of fish oil, which had been used 

 previously, I used tallow, with sufficient pine tar to make it stick the hair together, 

 but not enough to take the hair olf, as I was told it would. Lost none of about 90 

 mules and horses. — [Jona Pearce, Gwiney's, Va.
