peating the disbudding till it reaches the required height. A plant three 

 years from the cutting yielded in my greenhouse about 3 pints of fruit. —

Improvtments ivith regard to inducing Trees to form Roots, so as to ren- 

 der them independent of the Stock. — M. Dalbret remarks that pear trees, 

 more particularly those grafted on quince and apple trees, on doucin and 

 paradise stocks, derive great benefit when roots are emitted above the graft, 

 particularly in soils that are unfavorable for the longevity of these trees. 

 It therefore becomes desirable to assist or induce the formation of such 

 roots artificially, as follows : — When a plantation of these trees is made, 

 the grafts should be from 2^ to 4^ inches below the surface of the soil. 

 Two or three years after, in summer, when the sap descends in greatest abun- 

 dance, which is generally the case in July, the soil is removed, so as to 

 expose the point of junction of the graft and stock ; and immediately 

 above this, several portions of bark are removed Avith a sharp gouge, 

 about 4-lOths of an inch wide. The wounds are made in a perpendicu- 

 lar direction, and about an inch in length ; their form, from tliat of the 

 instrument, being concave, and so deep tliat a portion of the inner bark 

 may be removed ; and their number should of course be increased ac- 

 cording to the size of the tree, but so that not more tlian one fourth of 

 the bark shall be removed. (Hence four portions, nearly half an inch in 

 width, and an inch in length, would be removed at equal distances from a 

 tree eight inches in circumference.) The wounds must be immediately 

 covered with rich soil. Two quarts of decomposed cow dung, and six 

 quarts of maiden loam, well mixed, form a good compost for tiie roots to 

 strike into in the first instance. It is to be regretted that this mode of 

 invigorating the trees in our gardens and orchards has not been hitherto 

 employed. Some that have struck root naturally from above the graft 

 may be seen growing with remarkable vigor, whilst others adjoining, liv- 

 ing only on the stock, above which they form excrescences, languish dur- 

 ing a short existence. This mode ought to be adopted for all grafted 

 trees, destined to live in a light iiot soil. — (Id. 1844, p. 39.) 



JVitre a Remedy for Mildeu: — I wish to add a few facts to those already 

 stated with regard to mildew, and I hope to suggest a remedy. Having 

 in my conservatory, which may vary in temperature from 38" to 70°, an Aimee 

 Vibert rose, a Tea Hymenee rose, and a Microphylla rose, extremely subject 

 to mildew, I began about a year ago to try a remedy, which I think I must 

 have met with in the Gardcner^s Chronicle, viz. : to water them with nitre dis- 

 solved in water. The effect is, Aimee Vibert is quite cured, and Hymenee, 

 whose wood was almost destroyed by the disease, is totally free, and making 

 beautiful young wood ; the Micropliylla, though much improved in health, 

 has still a little of it left. I used one ounce of nitre to one gallon of 

 water, (the best I could get at the chemist's,) and about once in ten days 

 during the summer, and am just beginning again to do so. I should think 

 if the peach trees were well syringed witli the solution, taking care there 

 should be enough to water the roots, it would be effectual there also. I 

 tried sulphur without the least effect. — Id. 1844, p. 53.) 



Budding and Inarching the Grape Vine. — Wishing to increase the 

 number of Muscats of Alexandria and Cannon Hall Muscat grapes, I cut 

 down a few vines ; one half of them was budded and the other was 

 inarclied. To test the merits of each method fairly, both budding and 

 inarching were done at one period. The result is, that by the former
