 kingdom. The greatest drafts are upon the 

 group of Flagellata. which are so often pro- 

 vided with ehromatophores. He does not 

 take the Kadiohiria. however, with their 

 'yellow cells,' probably for the reason that 

 they are symbiotic forms. This will prob- 

 ably be the sticking point in such a classi- 

 fication, for even if the dividing principle 

 be admitted, the difficulty will ever be to 

 decide, in these low forms, what is true 

 chlorophyl formation and what symbiosis. 

 The discoveries of Famintzin and Entz show 

 that in many of the lower forms the presence 

 of chlorophj-1 is due to minute plant cells 

 which live independently of the animals 

 with which they are associated. Before the 

 classification can be complete it must be de- 

 termined for each form whether the chloro- 

 phyl is a symbiotic plant or a natural pro- 

 duct. Gary N. Calkins. 



Katims River Section of the Pernio- Carbonifer- 

 ous and Permian Bocks of Kansas. Charles 

 S. Prosser. Bulletin Geol. Soc. America, 

 Vol. 6, pp. 29-54. 1894. 

 In the above paper Professor Prosser con- 

 siders the historic section of the Vpper 

 Paleozoic rocks as exposed along the upper 

 course of the Kansas River. As is well 

 known, the early geologists of the State en- 

 gaged in a most animated controversj' over 

 the correlation of the geological formations 

 of this region. Altliough the investiga- 

 tions of Meek, Hayden, Hawn and Swallow 

 began more than thirty-five years ago and 

 were vigorously conducted for a number of 

 years, still the subject was not settled, and 

 many of the points at issue between the dis- 

 putants are still open for decision. 



The author descril)es various tj'pical geo- 

 logical sections as exj)Osed in the steep 

 bluffs of the Kansas river and its tribu- 

 taries, giving the distinctive geological 

 characters and fossils of the various divi- 



sions. In connection with this description, 

 there is a complete review of the previous 

 geological work, followed by a chart of tab- 

 ulated sections, on which the correlation of 

 the early geologists is indicated. 



Possibly the most interesting fact in the 

 paper to a geologist familiar with the region, 

 is the statement that the Cottonwood and 

 Manhattan limestones are the same. This 

 limestone, which is the most valuable stone 

 in the State for construction, has been ex- 

 tensively used, and the author states that 

 he has traced it across the country ft-om 

 Cottonwood Falls, on the Cottonwood River, 

 to Manhattan, on the Kansas River. An- 

 other interesting fact in reference to tlie 

 stratigraphical geology is the coiTelation of 

 the buff', magnesian limestones near Fort 

 Riley with those of Florence, in the Cotton- 

 wood Vallej'. 



In conclusion, it is stated that this is only 

 a preliminary paper and that the writer has 

 in hand the preparation of a report in which 

 a full description of the formations of Cen- 

 ti'al Kansas will be given, with the distri- 

 bution of their fossils and their general 

 correlation. 



NOTES AND NEWS. ' 

 FORESTRY AND ECONOMIC BOTANY. 



The steady increase of interest in for- 

 estry matters, so desirable and essential, has 

 recently become evident in many ways, es- 

 pecially in the Eastern States. New York, 

 Pennsylvania and New Jersey have taken 

 long strides in the right direction in the 

 shape of much needed legi.slation ; and the 

 establishment of forestry journals for the 

 promulgation of knowledge respecting the 

 nature and value of our native trees is a 

 step that will receive commendation from 

 thoughtfid people everj^vhei-e. The South 

 Jersey \\'oodmen's Association has shown 

 wisdom in securing an official organ through 

 which they may increase the scope of their 

 influence. The fir.st number of ' The New
