The pig with his individual pen can rove all 

 over the farm but he can't root under fences 



This Little Pig Went to Market— and 

 Carried Its Pen Along 



THE photograph above shows the con- 

 struction of a pen made for the individ- 

 ual use of a pig afflicted with Wanderlust. 

 It was effective in keeping the pig out of the 

 enclosed places and yet left him free to wan- 

 der anywhere he pleased. The rub came 

 when he tried to get under a fence or into 

 the chicken coops. It is the invention of 

 S. L. and J. A. Hirst, of Arkansas Pass, Tex. 



A Portable Alfalfa Mill Grinds Hay 

 for the Allies' Cavalry 



ALED al- 



B 



falfa hay 

 is shipped 

 from Califor- 

 nia to all 

 parts of the 

 world where 

 cattle or 

 horses are fed. 

 Yet this, 

 added to the 

 immense 

 home con- 

 sumption , 



could not use up all of the tremen 

 dous crop. 



The problem was solved a few 

 years ago by the invention of 

 a machine, now proved suc- 

 cessful, which travels from 

 field to field and converts 

 alfalfa hay into alfalfa 

 meal, using stems and all. 

 It is known as the portable 

 mill. 



The meal, itself, is not a 

 new product. Alfalfa meal 

 has been made for years in 



stationary mills; but the labor and cost of 

 hauling, and the loss of fine leafage in 

 handling, held back the industry The 

 portable mill did away with all that. 



The mill can be operated with steam or 

 electricity. A traction engine is preferred 

 because after a job is done, the engine can 

 hook on to the mill and haul it to the next 

 field. Three or four horses can haul it, 

 where no engine is used. Two men can 

 fold the machine up for traveling and can 

 set it up again in twenty minutes. When 

 folded, it is compact enough to pass 

 beneath telephone lines or trees, and to pass 

 over irrigation ditches, etc. 



The mill can be adjusted to sack the 

 meal, to blow it into silos, into barns, or on 

 the ground. An engineer, stacker, feeder, 

 sacker, sack sewer, water "boy, and horse 

 fork boy are required to run the outfit. 



Alfalfa meal is a valuable concentrate 

 alone, but it is usually fed in conjunction 

 with coarser ground feeds. When desired, 

 the mill can be adjusted to mix corn or oat 

 hay or other mixture. 



The meal is shipped at the grain rate, 

 which is from one-third to one-fourth less 

 than the hay rate. A ton of loose alfalfa 

 will occupy approximately 500 cubic feet; 

 baled alfalfa, from 215 to 225 cubic feet 

 The meal takes up only ioo cubic feet. 



The portable 

 alfalfa mill. 

 It is drawn 

 by engine 

 power from 

 field to field 

 and converts 

 the hay into 

 meal at a 

 fraction of 

 the usual 

 milling cost
