be too precise, I mean over nineteen, feet and six 

 inches. I stated the simple fact — if it seems incred- 

 ible it is open for inspection. There were three 

 shoots from the scion, one over seven feet, and one 

 over six feet, and the other about five feet, with two 

 or three side shoots from these, all from a single 

 scion. Will that answer ? I. T. W.

THE CANKER WORM. 



Frederic Howe, Danvers, Ms. — Tarring the 

 trunk of a tree is the remedy generally resorted to, 

 in order to prevent the female, who cannot fly, from 

 ascending the tree. We know nothing of the ex- 

 periment to which you refer of digging the ground 

 several times in the season, and especially just be- 

 fore it freezes. The worm descends into the ground 



from two to six inches, according to the nature of 

 the soil. 



Mr. Gregory, of Marblehead, in our volume for 

 1855, page 549, details a plan which has been suc- 

 cessful, and to which you are referred. 



MAGGOTS ON BEET LEA^'ES— LICE ON TREES. 



Can you, or your correspondents, inform me how 

 to preserve beet leaves from the ravages of the 

 maggot ? When it first came upon our beet leaves, 

 we thought it was a blight, but upon close exami- 

 nation we found it to be a maggot in the leaf be- 

 tween the two skins. 



Do you know of any thing that will kill lice up- 

 on apple trees without injuring the tree ? By an- 

 swering the above in the Monthly J\F. E. Farmer, 

 you will much oblige a SUBSCRIBER.

WOODRUFF'S NEW SELF-ACTING GATE. 



THE GATE AS IT APPEARS, CLOSED. 



These illustrations of a gate are not presented as 

 particularly designed for ordinary farm use, but for 

 front gates, and other important places. A gate of 

 this kind opening upon a highway where neighbors 

 persist in turning their cattle at large, must be ex- 

 ceedingly convenient. AVitb the common gate one 

 must either have a person go to it and open and 

 close it, or get out of the carriage, hitch the horse, 

 if he be a restive one, then drive him through, 

 hitch him again, and close the gate before he can 

 go on. This sort of tax we have been subjected to 

 for some years, and can, therefore, appreciate the 

 value of a self-opening and closing gate. 



Mr. Woodruff sometime since obtained a patent 



for an improvement in farm and ornamental gates, 

 and a full-sized working gate was on exhibition at 

 the late fair of the American Institute, at the 

 Crystal Palace, New York. Those who witnessed 

 the operation of that gate, expressed themselves 

 highly pleased with it, but experience has demon- 

 strated that self-acting swing gates are objection- 

 able, from their liability to damage by heavy gusts 

 of wind and gales. To remedy this and other de- 

 fects, Mr. AV. has invented the gate represented in 

 the annexed engravings, and has made an appHcation 

 lor a patent, through Fowler & Wells' Patent 

 Agency, of 308 Broadway, New York city. This 

 gate does not swing horizontally, but is composed
