218 HORTICULTURE [Bot. Absts. 



1536. Kirk, T. W. Control of brown-rot of some fruits. The past season's experiments. 

 New Zealand Jour. Agric. 18: 272-284. 1919.— See Bot. Absts. 3, Entry 1638. 



1537. Lamproy, E. Le navet en culture forcee. [Forcing turnips.] Revue Horticole 

 91: 230-231. Fig. 74-76. Feb., 1919.— This is a growing and profitable industry. The best 

 varieties for forcing and detailed cultural directions are given. About 2 months, from the 

 time of sowing the seeds, are required to mature the crop. Radishes may be grown in the 

 same frame with the turnips. — E. J . Kraus. 



1538. Lamproy, E. Culture des carottes de primeur. [The growing of early carrots.] 

 Revue Horticole 91: 219-220. Fig. 72-73. Jan., 1919.— There is a general discussion dealing 

 with the selection of varieties and the making and caring for the necessary hot bed. It is 

 suggested that radishes and lettuce be interplanted with the carrots. The seeds are sown in 

 the latter half of January. The radishes may be removed in 4 or 5 weeks after planting, the 

 lettuce about the middle of March, and the carrots about the end of April or the early part of 

 May. — E. J . Kraus. 



1539. Lamproy, E. Culture de crambe maritime. [Culture of sea-kale.) Revue Hor- 

 ticole 91:252-254. Fig. 82. Mar., 1919.— The general habitat and history of sea-kale 

 {Crambe maritima L.) as a pot herb are discussed. Root cuttings are most generally em- 

 ployed in starting new plantings, though seeds may be sown. Blanching of the new spring 

 growths is effected either by covering the plants with earth or by inverting a flower pot over 

 each. It is possible to force the plants in winter in the open ground by digging the soil 

 away from the plants, placing boxes and boards over them to exclude the light and then 

 filling the spaces with horse manure, or by means of a hot bed. More general use of this 

 vegetable is urged. — E. J. Kraus. 



1540. L'Esprit, A. Acacias parisiens. Revue Horticole 91:280. 1 -pi. May, 1919. — 

 Considerable error exists in the various accounts concerning the introduction of the locust 

 tree (Robinia Pseud-acacia) into Europe. It is here authoritatively stated that the seeds 

 were first secured from North America by Jean Robin in 1601, and a tree still standing in 

 the Jardin des Plantes (Paris) was planted there in 1636 by his nephew, Vespasien Robin. 

 A poem by M. Claro dedicated to the locust tree is included in the article. — E. J. Kraus. 



1541. Lewis, C. I. Some interesting phases of the pruning problem. Better Fruit 13 8 : 

 26-32. Feb., 1919. — This is a rather extensive review of the problems and fundamental 

 principles underlying different pruning practices. Quotations are made at length of a recent 

 bulletin of the Oregon Agric. Exp. Sta.: "Vegetation and Reproduction with Special Refer- 

 ence to the Tomato." The relation of carbohydrates and nitrates in the tree is considered as 

 the most fundamental factor in pruning. Effects of various types of pruning upon the tree, 

 particularly its fruitfulness, are discussed. — A. E. Murneek. 



1542. Melander, A. L. Why surrender to the codling moth? Better Fruit 13 5 : 33-34. 

 Feb., 1919. — A brief popular review of steps involved in combatting the codling moth. Early, 

 or "calyx," spraying is emphasized. — A. E. Murneek. 



1543. Meunissier, E. Un legume peu connu chez nous: le jet du houblon. [A vegetable 

 little known among us ; the young sprouts of the hop.] Revue Horticole 91 : 265-266. Apr., 

 1919. — Attention is called to the fact that the young spring shoots of the hop may be used 

 as a delicious vegetable. The use of the hop in this way seems to be fairly well established in 

 parts of Belgium, but is scarcely known in France. Brief cultural directions are given. 

 Prepared according to the ordinary methods used for asparagus; hop shoots are equal to that 

 vegetable. — E. J . Kraus. 



1544. Mottet, S. Neillia, Physocarpus et Stephanandra. Revue Horticole 91:236-238. 

 Fig. 77. Feb., 1919. — The article contains a critical discussion of the synonymy, species, 

 and forms of these genera, together with a notation as to their probable value as ornamentals. 

 There is also a brief citation of literature referred to in the discussion. — E. J . Kraus.
