Third, to do that which will endure. He will 

 have no part in oblivion, he is unwilling to be 

 forgotten, he can not abide the thought that his 

 work is to perish, that all that to which he has 

 given his time and strength and thought and 

 ppwer comes to an end simply because his body 

 dies. He wishes to project his temper and his 

 purpose and his plans into the future, to find in 

 this way and even here the beginnings of immor- 

 tality, so to labor that at least a part of his finite 

 product may be worthy to be woven in and in 

 with the divine plan and thus become lasting and 

 infinite.

TEE ELEt^ENTH INTERNATIONAL CON- 

 GRESS OF GEOLOGISTS, STOCKHOLM, 



1910 

 Eespectestg the progress of the arrange- 

 ments for this congress, which is to be held in 

 Stockhohn, August 18-25, the secretary-gen- 

 eral of the congress has given the following 

 information (February, 1910) ; 



The deliberations of the congress will prin- 

 cipally concern the discussion of the following 

 questions : 



1. The Geology of the Precambrian Systems. 

 — The discussion is divided into the debate of 

 the following special questions: (a) To what 

 extent can it be proved that the characters of 

 Archean rocks are due to a deep-seated meta- 

 morphosis? and (6) The principles of a classi- 

 fication of the Precambrian formations, espe- 

 cially as to what extent a classification after 

 age, of local or universal importance, can be 

 carried out. The following gentlemen have 

 hitherto held out short introductory lectures 

 for this discussion : F. D. Adams, Ch. Barrois, 

 F. Becke, U. Grubenmann, J. F. Kemp, A. C. 

 Lane, J. J. Sederholm and P. Termier. 



2. The Abrupt Appearance of the Cambrian 

 Fauna. — Messrs. Ch. Lapworth, G. F. Mat- 

 thew, A. Eothpletz, 0. D. Walcott and J. 

 Walther have promised contributions on this 

 subject. 



3. The Changes of the Climate Since the 

 Maximum, of the Last Glaciation. — As an in- 

 troduction to this discussion three Swedish 



scientists (G. Andersson, G. De Geer and E. 

 Sernander) published last spring comprehen- 

 sive descriptions of matters of fact observed 

 in Sweden, which are conclusive for the ex- 

 planation of the postglacial climatic devia- 

 tions in that country. These three essays were 

 sent to a considerable number of foreign sci- 

 entific men that have occupied themselves with 

 the question of postglacial climate, and these 

 gentlemen were at the same time requested to 

 cooperate in an international discussion of 

 this problem. The Swedish Committee de- 

 sires the cooperation in this international de- 

 bate in such a manner that from each country 

 but one report on the postglacial climatic 

 deviations observed there should be sent in. 

 In consequence of this invitation already sev- 

 eral treatises on the said subject have been 

 sent in and scientists from the following 

 countries have hitherto promised their co- 

 operation : Austria, Belgium, Canada, the 

 Cape Colony, Denmark, Egypt, England, Fin- 

 land, France, Germany, Hungary, India, Italy, 

 Norway, Eussia, Sweden, Switzerland. Ee- 

 ports on the arctic and antarctic regions have 

 also been received. 



All the treatises, sent in from the different 

 countries, will be collected in an autonomous 

 work: The changes of climate since the maxi- 

 mum of the last glaciation. This publication, 

 which will probably be ready in the course of 

 the month of April, will form the basis of the 

 coming discussion. This work will be sent 

 free of cost to the contributors. Besides, it 

 will also be procurable, at a price not yet fixed, 

 from the publisher, " Generalstabena Lito- 

 grafiska Anstalt," Stockholm 3. 



4. The Iron Ore Resources of the World. — 

 In the beginning of 1908 the committee of the 

 congress sent to the national geological insti- 

 tutions and to the mining geologists in the 

 different states invitations to take part in an 

 exhaustive investigation of the above question. 

 This request has everywhere met with so much 

 attention that, at present, reports from nearly 

 all the iron-ore producing countries of the 

 world have been received which will be col- 

 lected in one work : " The Iron-ore Eesourcea 

 of the World." This publication, consisting of
