THE AMERICAN ENTOMOLOGIST. 



covered in the Tertiaries of our western 

 Territories are proving to be wonderfully 

 rich in number of species and condition of 

 preservation. From a single small basin 

 exposed by a railway cut in the vicinity of 

 Green River Station, Union Pacific Rail- 

 road, in Wyoming, Mr. S. H. Scudder in 

 Fossil Insects of the Green River Shales 

 (Bull. U. S. Geolog.-Geograph. Surv. Terr., 

 iv, No. 4, pp. 747-776) enumerates eighty 

 species, representing all the orders of the 

 Insecta except Lepidoptera. An idea of 

 the richness of these beds may be obtained 

 from the statement, that a two hours' 

 search was rewarded by the collection of 

 fifty new species. We are glad to learn 

 that Mr. Scudder is engaged upon a general 

 work on our fossil insects, which will form 

 one of the volumes of the quarto reports 

 of the Hayden Survey — the beautiful 

 typography and illustration of which causes 

 us to regret the prospective speedy termi- 

 nation of the series. As the Tertiary 

 Shales of the Rocky Mountain region give 

 every promise of being richer in insect 

 remains than any other country in the 

 world, the material for this volume will be 

 more ample than any other student in fossil 

 entomology has been able to command. 



For the evident omission of reference 

 to much valuable work done during the 

 period reviewed, I ask indulgence. The 

 time that I had allotted to the preparation 

 of my sketch was found, too late, to be 

 quite insufficient for the extended bio- 

 graphical examinations required for even an 

 approach to completeness. I offer it only 

 as a partial sketch, and as such please 

 accept it. 



Statistics gathered for the forthcoming 

 annual report of the New-Jersey Labor 

 Bureau include reports from sixty-seven 

 silk mills, mostly in Paterson. The Pat- 

 erson mills alone employ 10,000 hands, 

 besides from 2,000 to 3,000 employed in 

 their own homes. The annual production 

 of these mills reaches the total of $14,- 

 000,000. — Scientific American. 



It is officially announced that the French 

 vintage for 1879 is 30,000,000 hectolitres 

 under the average of the last ten years. 



TWO DAYS' COLLECTING IN THE MAMMOTH 



CAVE, WITH CONTRIBUTIONS TO A 



STUDY OF ITS FAUNA. 



H. G. HUBBARD, DETROIT, MICH. 



During the past summer, while acting as 

 entomologist to the Kentucky State Geo- 

 logical Survey, I made, at Prof. Shaler's 

 direction, repeated examinations of the 

 limestone caves in the vicinity of Penning- 

 ton's Gap in the Cumberland Mountains 

 of Lee Co., Va., without however finding a 

 single specimen of any true cave insect, 

 except a cricket {Raphidophord). Being 

 dissatisfied with this negative result, and 

 anxious to test my powers in a locality 

 known to be inhabited by blind insects, I

determined on my return to make a short 

 visit to the Mammoth Cave. Accordingly 

 on the 19th of August, in company with 

 one other member of the Survey party, I 

 found myself in the stage coach, rapidly 

 traversing the ten miles of hilly country 

 that intervenes between the railroad at 

 Cave City and this world-renowned cavern. 

 We reached the hotel about six o'clock in 

 the evening, and, after supper, joined a 

 party which we found about to take ** the 

 short route," a tour in the cave of three and 

 a half miles and the same distance back, 

 making a walk of seven miles.
