■ Notes on the Tunis varieties of olives, It. :Makcili.e (Bill. Dir. Ai/r. ft Coin. 

 \Tuiiis]. 2 (1006), .Yo. .}i, ij]). 511-327). — In 1!M)(» olive plantations were estab- 

 lished at tbe colonial school of agriculture an<l at the experimental garden of 

 Tunis. At the pre.sent time over 80 varieties have been brought together, many 

 of which have fruited for the past 2 seasons. 



In this article the observations which have been made on these plantations 

 are ])rewented, including a study cf the relative value of the varieties of olives 

 utilized for pickling, the value and the yield cf those used in the extraction of 

 oil. and the quality of the oi! derived from Tunis olives. 



The article concludes with a discussion of the methods of propagating the 

 olive. The author is of the oi)inion that propagation by seed brings about the 

 best results. It is stated that the seed-grown trees are much hardier, more 

 resistant to disease, and more productive than i»lants propagated from cuttings. 

 The principal disadvantages of seed-grown plants ai-e the increased length of 

 time before they come into bearing, and the necessity of grafting. 



Work conducted at the government's American grape nurseries at Nicas- 

 tro and Palmi for the three years 1904-1906 (Bol. T'fpc. Miii. Af/r.. hidux. 

 r Coil). [Rome]. 2 (1!)07). .A'o. 1. pp. S'l-'i-'f). — This is a summary, together with 

 the more important data, relative to work conducted at the government nur- 

 series of Xicastro and I'almi in the testing and distribution of American grapes 

 for the 3 years 1904-lOOG. 



During this period a total of 81."!.ol.*.") cuttings and grafted i)lants were dis- 

 tributed fnmi the Xicastro nursery, and S!t(i,:!<;(» from the nursery at I'almi. 

 Tables are given showing the species and varieilics of stock plants grown, the 

 kind of soil, aud notes on vegetati*e conditions. The relative merits of the 

 different species, as to their resistance, adaptation, and value as stocks for 

 I'^untpean grapes are also di.scussed. 



Tables are .given showing the hybrids grown at both nurseries, the kind of 

 soil, the number of jilants of each variety, and observations as to vigor, fruit- 

 fulness, etc. The article also includes a discussion of the Koncet disease, and 

 notes on the school of grafting and the demonstration farm. 



Selection and preparation of vine cuttings, F. T. P.ioletti (CalifoinUt Sin. 

 Clrc. 26, i)ji. 7). — In this circular the author discusses the importance of a 

 proper choice of cuttings as a factor in determining the i)rotitableness of vine 

 yards, and makes,popular suggestions regarding the means of olitnininic cuttings 

 capable of growing into strong, heavy-bearing vines. 



Among the phases considered are the choice of locality, vineyard, vine, and 

 part of vine in selecting cuttings, together with the form and length of cutting, 

 and methods of conservation. 



Concerning the bagging of grapes, .1. I'.. I'illot (-/aril in. 21 (UiOl), .Yo. //.S'.?. 

 lip. un. IDS). — '^rhis is an account of tbe author's experiments in the bagging of 

 grapes conducted at Nancy, France. 



The principal advantage noted is that many of tlie finer varieties of grapi-s 

 which will not mature their fruit well in the open air in tbe cooler regions in 

 the eastern i)art of France, will yield s.'itisfactorily when tbe fruit is bagged. 

 While he found a number cf <li-ied and scalded grapes among those included in 

 bis liagging experiments, this is attribnt(Ml iirincijially to tbe lack of ventilation. 



In tbe author's spraying experiments, tbe onlin.iry nielbod of s|)raying grape- 

 vines with a solution of copper sulphate ai>peared ineffective as far as the fruit 

 was concerned, although it was found effective in preserving a healthy foliage. 

 Experiments in the dusting of grapes with dry copper suliihate were carried on 

 for a perio<l of 1-' years. It is sisited that the fruit matui-ed well and gave abun- 

 dant yields, while with the check jilals. wbicli were sprayed in tbe oiwlinary 

 manner, the grapes suffered severely from mildew.
