scientific farming. Another boy is a 

 plumber, and while he is telling of his 

 trade helpers are putting together 

 bathroom fixtures and sections of heating 

 plants. 



Dairying from beginning to end is 

 described by another boy while pretty 

 Indian milkmaids churn real butter and 

 place it in molds for marketing. How 

 to furnish a home is explained by another 

 lad, while girls help him arrange various 

 pieces of furniture in sectional rooms. 

 Here is a splendid house model and here 

 is a boy telling how it is erected. Helping 

 him are other carpenters and the house 

 shown is completed on the stage so far 

 as the woodwork is concerned, even to 

 placing lath for plastering and erecting 

 the inner staircases. 



Blacksmithing is another trade taught 

 at the Carlisle school, and the trade has 

 graduates. Accordingly, a blacksmith 

 shop is placed on the platform. Several 

 pieces of curved iron and wood are 



bolted together and wheels fastened to 

 the ends. Running-gears of a carriage 

 are thus made. Another lad grasps the 

 bellows- lever of a forge and soon flames 

 spurt upward. A smithy thrusts real 

 irons into the fire and presenth- two boys 

 are pounding out red-hot horseshoes on 

 a real anvil. Sparks fly into the air and 

 the ring of the anvil sounds throughout 

 the building. Another lad finishes the 

 shoes at a bench vise. 



Government officials are always in 

 attendance at these Carlisle commence- 

 ments. With school officials they occupy 

 seats until the Indian girl and boy have 

 had their say. Then come the addresses 

 of visitors, presentation of diplomas and 

 the remainder of the program. Such is 

 the way Indians graduate, displaying 

 the academic and vocational education 

 afforded by their training in such manner 

 as to mark the Indian graduation as the 

 most unique and interesting of all 

 commencements the country- over. 



AN ingenious 

 citizen of Illi- 

 nois has invented a 

 contrivance by 

 means of which his 

 chickens feed 

 themselves, thus 

 saving him the 

 trouble of early ris- 

 ing and feeding 

 them himself. As 

 the man remains in 

 bed his chickens 

 walk around the 

 contrivance in the 

 barnyard and in- 

 advertently step 

 on the ends of a 

 projecting board. 

 The weight of each 

 chicken is sufficient 

 to tilt the board, so 

 that the grain

the grain falls it is 



The chickens step on a projecting board 

 as they walk around the automatic feeder 

 and this causes the grain to fall from the top 



picked up by the 

 chickens and the 

 more chickens 

 there are operating 

 the automatic 

 feeder the faster 

 the grain falls to 

 the ground. 



When the first 

 chicken walked on 

 the projecting 

 board and discov- 

 ered that the faster 

 it walked the faster 

 the grain fell in 

 front of it, other 

 chickens fell in line 

 and it wasn't long 

 before the whole 

 barnyartl flock was 

 ni a r a t h o n i n g 

 around the con- 

 trivance, eating up thi' grain as it fell 



placed in the recei)tade at the top of 



the apparatus the evening before is and working up appetites for the next 



thrown to the ground. As fast as meal at the same time
