HUKTKUILTURE. 359 



Mayette and other good Freiu'h varieties of soft shell walnut. Annular or ring 

 budding is considered the safest jjlan of budding. Otherwise, the bud should be cut 

 deep and the wood gouged out, the object being to get more of the inner l)ark 

 surface. 



Notes on the caoutchouc trees of the Amazon, J. Hubek {Bui. Sue. Bot. 

 France, 49 {190J), So. 1-2, pp. 4-i-Bl) . — A discussion is given of the botany of the 

 various species and varieties of Hevea, Castilloa, Sapiuin, and other less well known 

 caoutchouc trees. 



The ether treatment of lilacs in the trade, F. Ledien ( Gartenwell, 6 {1902), No. 

 19, pp. 219-221). — The author states that the etherization of plants is being rapidly 

 adopted in the German trade. The etherizing room used by a grower of lilacs is 

 described. When etherized the middle of November, Charles X was ready to sell 

 24 days later; when etherized the first of December it was ready for market in 18 

 days. \\^ November, 50 gm. of ether per hectoliter were used, and in December only 

 40 gm. The cost of etherizing was about 2\ cts. per pot. In these experiments only 

 summer-planted lilacs -were used. In tests at the experiment station in Dresden, 

 both sunmier-planted and potted lilacs Avere used. The details of the station work 

 are withheld for future publication, but it is stated that old plants which had been 

 once etherized and forced, when heavily fertilized but not transplanted, responded 

 readily to etherization again, and by the end of October were in full foliage — an 

 important consideration when plants are sold in pots. It is stated that the foliage 

 nuist l)e kept confined within certain bounds by pruning, as otherwise the flower 

 buds are likely to remain undeveloped. 



Key to garden classification of roses, L. Barron {Ahier. Gard., 23 {1902), No. 

 377, ji. 171). — A key is given to summer flowering roses which bloom but once and 

 to sunnner and autumn flowering roses which bloom more or less continuously. 



Influence of stock on scion, J. Dallas {Amer. Gard., 23 {1902), No. 377, p. 

 166). — When Ophirie, a coppery colored and cup-shaped rose, was used as a stock for 

 Marechal Niel it transmitted a large percentage of its character and color to the latter. 

 The use of Lamaique, a pure white rose, as a stock for Marechal Niel resulted in buds 

 of normal size but ahnost white at the points. Cloth of Gold, when used as a stock 

 for ]Marechal Niel, produced flowers of the deepest yellow. 



Horticultural monograph of the genus Deutzia, E. Lemoine {Jour. Sac. Nat. 

 Ilort. France, 4- •'"'''■, "' {1!>0^'), Apr., pp. 2US-314, Jigs. 2). — This is confined to a study 

 of the different species and varieties cultivated in the garden from the horticultural 

 standpoint. 



Native vines in Wyoming homes, A. Nelson ( Wyoming Sta. Bui. 50, pp. 1-5, pis. 

 9, figs. 2). — This bulletin was written for the purpose of acquainting the peojile of 

 the State with the valuable native vines that may be used in the adornment of their 

 homes. (General descriptions and cultural directions are given for the American ivy, 

 Western clematis. River Bank grape ( 17//.S rulpina) , wild hops, and wild balsam 

 apple {Micrainpt'iis lobatu). Two valua])le introduced species are the well-known 

 morning glory and the moon vine, both of which do well in Wyoming. 



The "why" of the late planting of dahlias, J. W. Withers {Amer. Gard., 23 

 {1902), No. 386, pp. 318, 319). — The author states that he has been successful in 

 growing dahlias only when plantings were made after June 15. By planting late 

 the injurious effects of the usual summer drought are largely obviated and the plant 

 kept continually growing. This is considered to be the main reason of success in 

 late planting. 



Anewyellow calla, E. O. Orpet {Amer. (Jnrd., 23 {1902), No. 395, p. 463, fig. 1) .— 

 This calla is the result of crossing Ridiurdia elliotiana with li. alho-maculata. It 

 promises to be of considerable value for an outdoor sunmier plant. Dormant bulbs 

 planted about the latter part of May flower freely until fall, when the toj^s are cut 

 off with a scytlie, tlie tubers thoroughly lipened, and then stored in the cellar like 

 potatoes, until planting time again.
