•^ from the year-books published m other countries, which often 

 contain chiefly statistical material. The main object of the edition 

 of 1920 is to give the world public a general idea of the condi- 

 tions prevailing in the I^utch East Indian colony and of the 

 results achieved by Holland as a colonial power. Consecjuently 

 iTiucb that wa> included in the first edition, published in 1916,

 and Topography; Government; Health Regulations; .Agriculture, 

 including Forestry, which covers rubber planting; Commerce, 

 etc. It is the intention of the department to treat various .sub- 

 jects more in detail in succeeding year-books, so that in the 

 course of lime a set of year-books will contain a inore coinplete 

 representation of several important branches of service. The edi- 

 tion is published in Dutch and English. It is an imposing vohime, 

 beautifully illusfrated witli two-color half-tones from photographs

Owing to the increased expense of printing, paper, etc., this 

 little book has been somewhat modified and appears in stiff board 

 covers, instead of the green cloth binding used in the three 

 former editions. 



.As before, the contents cover tlie doings of tlie past year (in 

 this case 1919), as far as concerns rubber associations and dc- 

 partmsnts of agriculture, both without and within the Dutch 

 possessions in the East. There are reports of the activities of 

 experiment stations throughout the Netherlands East Indies, valu- 



able statistics of the number and extent of estates, experts trom 

 the various Java and Sumatra districts, trade and planting notes, 

 rules of the local planters' unions. Among the articles included 

 are: "Coagulants," by Dr. O. dc Vries ; "Spots on Sheets," by 

 J. C. llartjens, and "Spontaneous Coagulation," by Dr. O. de 

 Vries and VV. S|)oon. .\ review of rubber diseases during 1919, 

 lists of dellnitions and conversion tables of weights, measures, 

 prices are also inchidcil

 Compiled by K. Coclsl Het Ntd.Ind Rubbertijdschrifl, Batavia, 

 Java. Stiff board covers, 67 pages. 



Similar statistics had been published by the Netherlands East 

 Indies Association for the rubber trade, but after having pub- 

 lished data for 1917. the association stopped this work. Now 

 the publishers of the Nederlandsch-lndischtijdschrift have taken 

 over the publication of a similar little hook and intend to publish 

 revised editions every year. 



The appearance of the book has been .greatly improved and 

 pains have been taken to get as much and as accurate information 

 as possible. .Altogether 576 estates in the Netherlands East 

 Indies, covering an area of 486,149 bouws (1.754 acres equals 

 one bouw) and having had an estimated crop of 71,067,760 kilos 

 during 1920, are treated. First come the Javanese estates grouped 

 in alphabetical order under the various residencies. The dis- 

 tricts in Sumatra, then Borneo and Celeljes follow. Next M the 

 name of each estate are the name of the manager, address, total 

 area, area planted to Hevea, area planted to Ficus. area in bear- 

 ing (all in bouws), output of 1918, output of 1919, estimated 

 output of 1920 (ill kilos), dividend for 1917, dividend for 1918, 

 capital, proprietor and attorney in the Netherlands East Indies. 

 .As all this data is given for each estate in one compact para- 

 graph with no special indication of its meaning except a figure, 

 a loose card with the explanation of these figures is added with 

 each copy of thi' liook.

.A very practical and comprehensive plan of cost accounting 

 applicable to plants engaged in proofing of clotli, whether devoted 

 wholly or partially to such work, is graphically set forth in this 

 timely contrilnition to the literature of the rubber industry. It is 

 the aim of the authors to correct the demoralizing effect of the 

 haphazard pricing of products due to a lack of proper knowledge 

 or to ail over-eagerness of many manufacturers to get business. 

 Even a casual glance at the method presented will reveal many 

 important factors of cost that lie between gross sales and net 

 profits. Particularly serviceable is tlie formula showing in detail 

 the successive stages of cost accumulation, and the mode of ana- 

 lyzing and recording each item of expense. Especially valuable, 

 too. arc the charts for ledger accounts, plan of cost control, and 

 the f.-.rm- of factorv order cost sheets.
