FuoM '^N m. Kobei-tson, (^akville. We 

 think it equally good with the Field 

 Force Pump of Rochester. Mr. McD. 

 Allan recommends Brooks' Champion, 

 for sale by Beecher liros., London. It 

 only costs §3.50, and may be used for 

 spraying either large trees, or small 

 bushes. 



Bark lice. 



49. In till- April imiiibcr I iv 

 tice ytiu ifcniiiiiit'iKi noft soa) 

 and wa.><hiii),' soda for bark-lice on 

 apple trees. What proi)oiti(jnrs 

 jf these should I use and is it 

 too soon to put it on now ?— .J. 

 H., Port H«i». 



We use lialf a pound of 

 washing soda to an ordinary 

 wooden pailful of water, 

 mixing in tlie soft soap 

 ad libitum. Either of 

 these substances are effec- 

 tive remedies by them 

 selves. The application 

 should be made about the 

 first of June, at the time 

 when the almost micro- 

 scopic young lice hatch out 



and leave the old scale in search of 



new quarters. 



The Onion Maggot. 



.50. Is there any effccti vt^ renu'dy for the onion 

 maggot? Last year I tried a strong solution 

 of tobacco and soot in water, hut without avail. 

 W. H. F., Peterboro. 



Prof. Lixtner, New York State 

 entomologist, recommends spreading 

 gas lime fresh from the works, upon the 

 ground in the fall, at the rate of 200 

 bushels per acre. The maggots pass 

 the winter near the surface of tiie 

 ground in a chrysalis state and the gas- 

 lime would kill them. Mi.ss Omerod, 

 an English entomologist of note, has 

 been successful in keeping off the mag- 

 got by siniply earthing up to the neck 

 each bulb, sometimes growing them in 

 trenches to favor this operation. A 

 Massachusetts gardener has for forty 

 years used a strong decoction of bur- 

 dock leaves with success. He runs 



them through a liay-cuttei-, pounds 

 tfiem to a pulp, and adding water, leaves 

 them standing over night. He applies 

 by pouring the mi.xture along the rows. 

 Prof. Itiley recommends spraying the 

 onion patch with kerosene emulsion. 



The Annual Report. 



.")1. Has the aiuuial report yet been distri- 

 buted ? Is there no way of getting it out earlier 

 for study amid the comj)arative leisure of the 

 winter ? Now it conies in the very press of ou 

 door W()rk, and all careful and thoughtful per- 

 sual of it is out of the ([ueBtion, and by next 

 winter it will be a trifle stale.— C. n. M. 

 KingxvUlc, Ont. 



\ The Keport has been in the printer's 

 \ hands since December. The proofs 



(have been carefully revised and indexed 

 by the writer, and we are in daily ex- 

 pectation of its readine.ss for distribu- 

 tion. Probably it will be in the hands 

 of our readers before these pages. We 

 will do our best to have it issued earlier 

 in future. 



Training a Grape Vine. 



52. .SiK, — Would you kindly inform me in your 

 next issue wliich is the better method of train- 

 ing tile grai)e vine— on the upright or on the 

 arbor trellis ?— A. M., Brampton. 



For field culture, or in a vineyard of 

 any size the upright trellis is decidedly 

 tha most convenient, for pruning and 

 for laying down in winter, find for 

 gathering the fruit. But for a few 

 vines in a garden the arbor trellis is 

 much more artistic, and gives an oppor- 

 tunity for training much longer arms 

 of bearing wood to each vine. 



Greenhouses 



53. Can you tell me of a work on the construc- 

 tion of a small greenhouse? — .1. M., Jiou^mav- 

 rille. 



Volume VIII. of the Canadi.\n 

 Horticulturist, p. 88, et sft/, has a 

 good article with working plans on this 

 very subject. 



Slag as a Fertilizer. 



54. Can you give your readers any informa-

 amongst the farmers in Kngland called liasic
