1. All parties whose interests are affected by a specification, 

 should have a voice in its preparation. 



2. The limitations contained in a specification may be derived 

 from any source of knowledge and the tests may be microscopic, 

 physical or chemical. 



3. The specification should contain all the information which 

 is needed by those who are to enforce it; this includes the 

 chemist, the engineer, the purchasing agent, and the superin- 

 tendent. 



4. The service which the material is to perform, in connection 

 with reasonably feasible possibilities in its manufacture, should 

 determine the limitations of a specification. 



5. Proprietary articles and products made by processes under 

 tlie contro! of the manufacturer cannot, from the nature of the 

 case, be made the subject of specifications. The consumer may, 

 liovvever, determine the chemical and physical properties of any 

 preparation ami incorporate these in a specification, in case that 

 substance has given eminent satisfaction. 



6. The sample for testing must always be taken at random by 

 the consumer. The amount of material represented by one 

 sample must be determined by the nature of the material, the 

 value of the material, its probable uniformity, and its importance. 



7. .Average samples, made up of a number of samples, should 

 only l)e prepared in cases where the limits of the specification 

 are so narrow that they do not cover the ordinary irregularities 

 of good practice in manufacture. 



8. Re-tests of material which has once been rejected should 

 be allowed only on very good grounds. They are justified when 

 there is a doubt as to the exactness of a test. 



9. If it is desired to sell rejected material to a consumer, a 

 concession in price must be made, but rejected materials should 

 never be used in places where they may endanger life and 

 property, i 



10. When a consumer has purchased material on specification 

 it i.> unfair to ask of the manufacturer anj' guarantee covering 

 the behavior of the material in service. 



11. It should as a rule be unnecessary to mark rejected 

 material, when dealing with reputable firms, but if necessary an 

 inconspicuous private mark may be applied. In any case the 

 manufacturer should be obliged by contract to pay return freight 

 on rejected shipments. 



12. Specifications should be examined, and if necessary re- 

 vised, six months after they have first been put in force. This 

 will allow for the introduction of the knowledge and experience 

 gained by actual usage. 



13. In testing materials, if the results are just outside of the 

 prescribed limits, an allowance should be made for the probable 

 error in the method of making the test, but gross discrepancies 

 should in every case lead to a rejection. 



14. A complete workable specification should combine within 

 itself the harmonized antagonistic interests of both the producer 

 and the consumer. It should have the fewest possible require- 

 ments consistent with securing satisfactory material, should be so 

 comprehensive as to leave no chance for ambiguity or doubt, 

 and, above all, it should embody within itself the results of the 

 latest and best studies of the properties of the material which it 

 covers. 



NEW TRADE PUBLICATIONS.

CALENDAKS FOR 1911. 



One of the handsomest calendars for the new year comes from 

 the Adamson Machine Co. (Akron, Ohio). The large card on 

 which are attached monthly tear off leaves is embellished with 

 a reproduction by color photography of an original painting by 

 Dobson, entitled "The New Arrival." 



The calendars sent out by the different rubber companies are 

 not only more artistic and attractive in appearance year after 

 year, but they are beginning to cover more wall space. The 

 new calendar of the Lambertville Rubber Co. (Lambertville, 

 New Jersey) is 24 x 36 inches. Its embellishing feature is "The 

 Lambertville Girl" — a picture in colors, life size, of a young 

 woman equipped for golfing.

 booklet labeled "Reminder and Daily Memoranda," in flexible 

 leather, vest pocket size, containing, in addition to calendar and 

 numerous details valuable for reference, a space for entries for 

 every day of the year.

 monthly tear off leaves, mounted on a brass stand which may be 

 used permanently by the substituting of new calendar pads. 



The calendar of the \\estern Rubber Co. (Goshen, Indiana) 

 is adorned with a reproduction, by color photography, of a 

 painting entitled "Morning," showing a scene in the vale of the 

 Treignac, France, by the notable artist Gaston Anglade.

 send a calendar on a card 6;/4 x 9-54 inches, carrying a picture 

 in colors, "My Chauffeur," from a painting by Philip Eoileau, 

 the chauffeur in this case being a beautiful girl. It is one of the 

 most attractive calendars received. 



Meyer Cohn, a waste rubber merchant of Hanover, Germany 

 • — with United States offices at No. 117 Chambers street, New 

 York — sends out a handsome "Notiz-Abreiss-Kalender fiir das 

 Jahr, 1911," suitable for wall use, and containing a tear off 

 leaf for each day in the year, with spaces for daily memoranda. 



A PAN AMERICAN CONFERENCE. 



AN invitation comes to The Ixijia Rubber World to be repre- 

 sented at a "Pan .American" commercial conference, to be 

 held under the auspices of the Pan American Union, in its 

 new building in Washington, during the week of February 13-18. 

 The discussion is planned of an expansion of reciprocal trade 

 relations between the United States and the twenty Latin-Amer- 

 ican countries, to be participated in by representatives of com- 

 mercial and other interested organizations, private firms, educa- 

 tional institutions, and so on. It is expected that the Rubber 

 Club of America will be represented, and this journal hopes that 

 the proposal of this conference, by the able director general of 

 the Pan American Union, the Hon. John Barrett, will meet a 

 cordial reception among those for whom it is intended.
