 [ I'lruilvitiija Mainnil.s, JDOtj, \(>. I. pj). \'J 1 1 -{-,i<!!), pis. 2.'i, figs. 1, maps 7). — 

 This is volume 1 of a series of niaiiu.ils on trojiical botany, entomology, agri- 

 culture, and horticulture, which are to lie written by the staff of the I'eradeniya 

 institution and other writers and laiblished at intervals. It contains the ofHcial 

 account of the Ceylon rubber c\hiI)ition held in the Uoyal Botanic (Jardens, 

 I'eradeniya, September, T.KXi. 



In the several lectures delivered at the exhibition the various phases of 

 rubber, from cultivation to vulcanization, were considered, together with a dis- 

 cussion of cotton, tobacco, camphor, lemon grass, and citronella. These lectures, 

 together with the discussions following them, have been revised and arranged 

 in logical order with the purpose of making this account a standard treatise 

 upon the rul)ber industry as it exists at present. The cultivation of rubber in 

 Ceylon :ind other countries is described, the treatment of diseases, catch crops 

 for rubi)er plantations, tapping knives, machinery for the treatment of latex or 

 rubber, shipping, marketing, vulcanization, etc. 



Para rubber: Distance and interplanting, II. Wright (Trap. Agr. and Mag. 

 I'ltjIoH Agr. .svx-., 2.S (1907), Xo. 1. pp. 2-!)). — The author discusses somewhat at 

 l(Migth the following 5 systems of planting I'ara rubber trees : Close planting — 

 Iiermaiient; close planting and thinning out; wide planting — permanent; wide 

 planting with catch and inter-crops, and interplanting with herbaceous and 

 arborescent plants. 



The permanent — close and wide planting systems — are not considered of much 

 value, since the former is said to be wrong in principle and the latter extremely 

 wasteful. The author is in favor of those systems which allow the provision 

 of increased root area as the rubber trees advance in age and increase in size. 

 This may be brought about by thinning out the rubber trees, inter-crops, and 

 other plants fi-om lime to time. 



Cultivation of Manizoba rubber (Manihot glasiovii), R. U. Uribe (Bol. 

 tioc. Agr. Me-ricuiia. .31 {1901) Kos. 7, pp. 121-12-',; 8, pp. 1J,3, i^//).— An ac- 

 count of the cultivation of the "Manizoba" rubber tree in Brazil, including a 

 Iiotanical description and notes on adaptability to climate and soil, planting, 

 i-nltivation, methods of exploitation, and yields. 



The autlior considers tlie "Manizoba," which is generally known as Manihot 

 glasiorii. or the Ceara rubber tree, especially adapted to the conditions in Co- 

 lombia, where it is believed that the financial returns would be greater than 

 Irom cotton, sugar cane, or coffee, especially if the trees were planted by small 

 farmers who could manage and gather the rubber themselves. 



The bamboo and its uses, Ergates (Xatal Agr. Jour, and Miii. Rcc, 9 

 ( I9()(;), Xo. 12. pp. in.'t-ll'il, pi. 1). — The bamboo is said to be of great value 

 as a wind-break for fruit crops and as material for making fruit boxes and 

 ladders, as well as in the construction of walls and doors for sheds and stables, 

 water tnmglis for iioultry. iind liaiidlcs for hnniniers and other small implc- 

 nicnts. 



The method of making liamhoo fruit boxes is described. The ends of the 

 iiialler boxes are made of solid wood, while those of the larger boxes are made 

 "f s(|uare frames filled in with sm.-ill bamboo slats, with the sides of l)amboo 

 slats. .V box 2 ft. L' in. by 1 ft. (! in. and n in. deep is said to cost about ."O 

 cents. .\t present the linnted supply of bamltoo does not warrant the manu- 

 facture of these boxes as an iiidciicndcnt liusiness.
