 and Co-operative Societies; Sanitation and Hygiene on Tropical 

 Estates; Legislation Against Plan' and Pests: Cotton 



and Cotton Cultivation, and Fertility of Soils in the T;. 

 The fact that these papers were prepared and discussed by 

 authorities on tropical agriculture from all over the world makes 

 the book of value as a record of expert opinion on many of the

TABLES OF PROPERTIES OF OVER FIFTEEN HUNDRED COMMON 

 Inorganic Substances. By Wilhelm Segerblom, A.B., Instructor in 

 Chemistry at the Phillips Exeter Academy. 1909, Exeter, New Hamr- 

 •.hire. Exeter Book- Publishing Co. [Cloth, Svo, 144 pp. Price S3, 

 postpaid.] 

 The author designed this work as an aid for students in 

 analysis in corroborating their results. He groups the metals 

 in six sections, according to Fresenius, and arranges the de- 

 scriptive tables of properties on a very rational and convenient 

 plan, facilitating reference. With the arrangement used it is 

 possible not only to find all the salts of any one metal together, 

 but also to compare any salt of the metal in question with the 

 corresponding salt of each of the other numbers of the group 

 to which the metal belongs. It is possible also to compare the 

 salts of any group with the corresponding salts in the other 

 five groups. The properties given include state, color, luster, 

 crystalline form, deliquescence, efflorescence, stability in air. 

 action on test paper, melting point, behavior when heated, solu- 

 bility in water, alcohol and acids, and any other properties 

 characteristic of the substance in hand. For convenience the 

 formulae, chemical names and the common names are all given 

 The index is designed to locate a salt when only the common 

 name is known. 



The work is a valuable addition to the analyst's library. 



RUBBER IMPORT AND EXPORT REGULATIONS. 



A NUMBER of developments occurred during the month of 

 **■ June, relating to the imports of crude rubber from the 

 East and to the export of rubber manufactured goods. In si ime 

 respects the regulations have been slightly relaxed, and in other 

 respects they have been somewhat increased. 



RUBBER GOODS MAY NOW BE SHIPPED TO ITALY. 



The British Consul General at Xew York gave notici 

 May 28 that the British Foreign Office, in view of the fact that 

 Italy had joined the Allies, had consented to lift the em 

 on rubber shipments to Italy. lie authorized the altering of 

 the guarantees given the British government by the insertion 

 of tin- words "or Italy" after the word "Russia" in the sixth 

 paragraph of the guarantees which were agreed upon last Jam 

 ary between the British government and the representatives of 

 the Rubber Club. When this change is made the paragraph will 

 reail : 



"We will not sell any manufactured or partly manufactured 

 rubber goods to any person in the United State without satis- 

 tying ourselves that there is no intention on his part to export. 

 or resell the same for exportation, to any countries in Europe 

 other than Great Britain, France, Russia or Italy, otherwise than 



b\ shipping to the United Kingdom and r< - r om there, 



under license to be obtained for export therefrom." 



PB il i.i 1\ i \-I RUBBER IS REJECTED. 



On the third .if June, Secretarj Vorhis, of the Rubber 



circular addressed t" all the members of the rubber trade 

 regarding the method of procedure in case for anj reason rub- 

 ber which had been released for their account was rej. 

 The following paragraphs give the essential matter of the cir- 

 cular: "The attention of manufacturers is called to the fact 

 that they are accountable for rubbei rele: leir account, 



and that in case of rejection of rubber, in whole or in part, the 

 manufacturers must immediately notify the secretary of The 

 lub of America. Inc. In such cases, the secretarj 

 promptly receive from the seller of the rubber either a 

 new guarantee from a new customer for tin delivery of tht 

 ted rubber to them. ,ir the seller must put the parcel in 

 (pending the resale of same) with The Rubber Clul of 

 America. Inc." 



I PORTING 1 3 CON! UNING ONI 5MA1 QUANTITY 



OF RUBBER. 



The British government lias announced that the rubber guar- 

 antee signed by rubber manufacturers, stipulating that shipments 

 of rubber manufactured goods to neutral European countries 

 should be made via England, is not intended to apply to articles 

 i personal or household use containing only a small quantity 

 of rubber, such, for instance, as suspenders, garters and type- 

 writers. 



The Control Committee of The Rubber CI t( ver, sug- 



gests that even in such cases, manufacturers notify the British 

 Consul General at Xew York of all such shipment' which they 

 intend to make direct to neutral European countries 



I LEARING PLANTATION RUBBER FROM THE DUTCH EAST 

 INDIES. 



On June 24, the secretary of the Rubber Club sent a cii 

 to crude rubber importers, brokers and dealers, referring to the 

 import of rubber from the Dutch East India plantations, in 

 which the following paragraph appears : "Realizing that the 

 British government wishes the most accurate record possible 

 kept of plantation rubber arriving in this country from the Dutch 

 Indies, the Rubber Control Committee has unanimously 

 passed a resolution recommending that all crude rubber im- 

 pi rters, brokers and dealers in this market file the British rub- 

 ber guarantees for all such rubber with The Rubber Club of 

 America, Inc., and have its disposition recorded in exactly the 

 same manner as though the rubber had been consigned to H. 

 B. M., Consul General at Xew York." 



THE EMBARGO FUND PAYS \ DIVIDEND. 



It will be recalled that when the work of removing the em- 

 bargo on plantation rubber was first undertaken by the Rubber 

 Club last January, it asked for voluntary contributions from 

 members of the club to defray the necessary expenses of the 

 Embargo Committee in conducting its negotiations with the 

 State Department and the British government. As the fees 

 received in connection w ith the work of the committee have for 

 some time fully covered the expenses involved, the Executive 

 Committee voted at its meeting June 11. 1915. to refund pro rota 

 to the contributors the unexpended balance now remaining of 

 that fund. 



The total amount subscribed was $3,118.96. The expenses of 



the committee amounted to $1,745.32. leaving a balance of $1,- 



; r.5(4. This was returned to the original contributors by the 



urer of the club on June 24 and amounted to a refund of 



practically 44 per cent. — quite a handsome dividend. 



The India Rubber, Gutta Percha & Telegraph Works Co., 

 Limited, of Silvertown, England, has announced that owing to 

 the increased cost of production because of the higher prices of 

 materials and labor consequent upon the war. it has been found 

 necessary to make a 10 per cent, advance in the price of its 

 cutta percha. india rubber, silk and cotton covered wires.
