plants by a small, redish-brown moth. The larva attains its full growth in June, 

 when it is nearly half an inch long, of a brownish or greenish color, with a shin- 

 ing yellowish-brown head. The larva pupates within the rolled leaf, and about 

 mid-smmer emerges as a moth. These moths deposit eggs for a second brood 

 of caterpillars that feed upon the leaves late in summer, changing to pupse early 

 in autumn, and, passing the winter in that condition, emerge again as moths the 

 following spring, thus completing the cycle of the year. In the Southern States 

 there are three, and possibly four broods a year. 



Remedies. — The best way to destroy this pest is to mow the field soon after 

 the strawberry crop is gathered, and after leaving it a day or two to become dry> 

 burn it over. This will destroy the leaf-rollers as well as several other kinds of 

 insects, and the spores of fungus diseases. It is sometimes necessary to scatter 

 a little straw over the field where the leaves are not thick enough to burn well. 

 The plants will not be damaged, but will soon send up a new lot of leaves that 

 will grow rapidly, and be free from insect and fungus attack. If for any reason 

 this method is not desirable, the insects of the second brood may be destroyed 

 by spraying or dusting the plants in August with some poisonous insecticide." 



This insect is also described and figured in that excellent work, " Insects 

 Injurious to Fruits," by Dr. Saunders. Practically the same remedies are 

 recommended. 



In this connection I wish to emphasize the benefits derived from treating 

 a strawberry bed affected with rust in this way. Two years ago I burned every 

 alternate row of plants in our experimental plots, and found the succeeding 

 growth to be exceedingly healthy. The plants came through the winter uniformly 

 in a very successful and satisfactory condition. I believe it to be an excellent 

 practice in large commercial plantations. 



Yours very truly,

PLOWING WITH THREE HORSES ABREAST. 



One on the furrow and two on the land, I use the whiffletree pictured. 

 The long whiffletree ^ is 4}^ ft. long, the main clevis a being 18 in. from one 

 end. The doubletree, e, is 3 ft. long, and the singletrees,^ are each 20 in. in 

 length. To hitch up, fasten the clevis, a, to the plow clevis ; the short end of 

 the long whiffletree goes next to the plowed ground. Then fasten the doubletree 

 to clevis b, and one singletree to clevis c. 

 Three clevises will be required on the long 

 whiffletree and three on the doubletree 

 Both larger trees will require five open 

 rings, and if the plow is fastened at a with ,

an open ring, another is necessary. Such 



a rig will answer for a team weighing up to 1200 lbs- to each horse. For 

 heavier horses, the proportion of the trees must be enlarged. This rig can be 

 used for harrowing, rolling or dragging land. — Farm and Home.
