THE CONTRACTOR'S DUMP WAGON. 



The Contractor' s Damp Wagon, recently 

 put on the market by the F. C. Austin 

 Manufacturing Company of Chicago, and 

 illustrated above, is something that con- 

 tractors will appreciate, and the reputation 

 of the manufacturers is a guarantee that 

 the wagon will be well made. 



A serious difficulty with all "bottom- 

 dump " dump wagons previously con- 

 structed has been that the doors being 

 hinged, and therefore laterally rigid, fre- 

 quently stall the team on the dump. 

 When it is understood that all dumps, 

 whether of earth, rock or garbage, are very 

 uneven, and that one or more of the 

 wheels, when the load is being dumped, 

 rests in a pocket or low place, the objec- 

 tion to the hinge doors will be apparent ; 

 for example, should the hinge door strike 

 a load previously dumped, or any obstruc- 

 tion before the load is fully discharged, it 

 is necessary to move in some other direc- 

 tion to release the door, which, as will 

 be understood, cannot be done without 

 heavy pulling and a strain on the team ; 

 again, with one of the front wheels in a 

 low place, the front end of the hinge door 

 is likely to run into a previously dumped 

 load or obstruction, which stops the team, 

 as well as wrenches the box, tearing off 

 the hinge door. 



The doors of the Contractor's Dump 

 Wagon, illustrated above, when closed, 

 make a comparatively tight bottom ; when 

 open, they can oscillate in any direction, 

 thereby adjusting themselves to the debris 

 or obstruction underneath. 



INCREASING USE OF WINDMILLS. 



The fact that an Aermotor has just been 

 purchased by the authorities of Garden 

 City, Kansas, where all styles and varie- 

 ties of windmills are in operation, goes to 

 show that they consider the Aermotor the 

 best manufactured, and fully able to stand 

 the severe work required in raising water 

 for irrigation. For this purpose a strong 

 well-built mill is needed, as the work is 

 very heavy, much more so than any task 

 to which the windmill has heretofore been 

 harnessed, and the past few years have 

 demonstrated that the Aermotor is able to 

 meet the requirements. It is increasing in 

 popularity constantly, and in spite of the 

 prevailing hard times, new factories and a 

 larger force of workmen are needed to 

 meet the demand. Arrangements are now 

 being made tq add another six-story build- 

 ing to the plant. 



The Aermotor Company of Chicago is 

 fully alive to the importance of irrigation, 

 and has issued a special catalogue on this 

 subject, whcih will be mailed to any ad- 

 dress free, provided THE IKRIGATION' AGE 

 is mentioned when writing for it. 



A USEFUL INSTRUMENT. 



The Jackson Grade Level Company has 

 recently made a very important improve- 

 ment in their level by adding a horizontal 

 circle, which is attached permanently to 

 the shoulder of the tripod head. This is 

 graduated into degrees, and a pointer is 

 attached to the level above, thus enabling 

 anyone to run accurate lines straight or at 

 any angle without the trouble of measure- 

 ments. 



Supt. W. F. Cash, of the Experiment 

 Station, Idaho Falls, writes of this level as 

 follows: " I have an instrument with which 

 I can turn off a right or other angle, and 

 find it very convenient in laying out irriga- 

 ting ditches, where a series of small ditches 

 take off from the main ditch. It is also 

 very handy for laying off land for plowing, 

 setting fences, etc. The new improvement 

 adds greatly to the usefulness of the level, 

 especially in an irrigated country."
