operate mainly on old culm banks, and an in- 

 crease of 16 per cent, in the quantity of coal 

 dredged from rivers. 



The production in the Lehigh region was 

 10,929,055 gross tons; in the Schuylkill region, 

 23,659,448 tons; in the Wyoming region, 43,- 

 111,732 tons; and in Sullivan County (Ber- 

 nice Basin), 494,848 tons. 



There was a large decrease in the number 

 of men employed in the production of anthra- 

 cite in 1916, and the output was maintained 

 only through an increase in tlie number of 

 working days. The number of men employed 

 in 1914 was 179,679; in 1915, 176,552; and 

 in 1916, 159,869. The average number of days 

 worked was 245 in 1914, 230 in 1915, and 253 

 in 1916. The average output per man per 

 day in 1914 was 1.84 gross tons; in 1915, 1.96 

 tons, and in 1916, 1.93 tons. The average out- 

 put per employee for the year was 451 tons 

 in 1914; 450 tons in 1915; and 489 tons in 

 1916. 



ANIMAL COLLECTIONS FROM AUSTRALIA 



The animal collections of the Zoological 

 Park have been enriched by the arrival of 

 another great " caravan " from Australia. 

 After six months of diligent effort, and gen- 

 erous expenditures of money, Mr. Ellis S. 

 Joseph brought together and successfully 

 transported to New York the largest collection 

 of rare species of mammals, birds and reptiles 

 that ever came to America. The common spe- 

 cies, such as for years have been coming to us 

 through the regular European channels, are 

 conspicuous by their well-nigh complete ab- 

 sence. 



Naturally, the officers of the Zoological So- 

 ciety feel measurably elated over this coup, at 

 a period of great depression in the wild-animal 

 supply from other sources. The receipts from 

 England are very trifling, and from the con- 

 tinent of Europe nothing whatever comes. In 

 fact, in America the German wild-animal 

 business is thoroughly dead. Our further 

 operations in South Africa must be postponed 

 until after the war. 



Encouraged through his previous reception 

 by the Zoological Society, Mr. Joseph re- 



doubled his former efforts to bring to America 

 something worth while. The collection which 

 he landed in Victoria, B. C, a month ago rep- 

 resents a large outlay in money and effort, and 

 great scientific value. Of that importation 

 the Zoological Society has purchased mammals, ' 

 birds and reptiles to a total cost of about 

 $6,000. The Philadelphia Zoological Society 

 has purchased $3,000 worth, and other pur- 

 chases are proceeding. 



The following list shows the newly acquired 



ma mm als : 



1 thylaoine, 

 3 hyraxea, 



2 water mongooses, 



1 echidna, 



2 rabbit-eared bandicoots, 



2 West Australian rat kangaroos, 



1 tree kangaroo, 



3 yellow-footed rock wallabies, 



2 Woodward kangaroos and young, 

 1 wallaroo, 



1 brush-tailed wallaby, 



2 short-tailed wallabies, 



1 Paddy Mellen wallaby, 



2 rufus-necked wallabies, 



2 Tasmanian black phalangers, 

 6 spotted phalangers, 



3 dusky phalangers, 

 3 gray phalangers, 



3 Papuan phalangers, 



1 Australian phalanger, 



4 marsupial mice, 



3 Australian water rats. 



The majority of our accessions will be found 

 in the large bird house, the small deer house, 

 the reptile house and the small mammal house, 

 but the thylacine is in one of the small bear 

 dens. Each new species is marked by a red 

 label reading "Eecent Accession." Inci- 

 dentally it is to be noted that our total kanga- 

 roo collection is believed by Mr. Joseph to be 

 the most extensive series ever brought to- 

 gether. It will be found in the small deer 



house. W. T. HORNADAY,
