COST. 



Changes which had to be fnade, trying different styles of 

 elbows and unions, testing different sets of nozzles, together 

 with an accident to the carrier, and the extra work required to 

 put parts together the first time, brought the cost of this ma- 

 chine nearly to the |300.00 mark. At the outside the parts 

 ought not to cost more than as follows: 



Wheels $16 00 



Tank 12 00 



Pump, iron triplex 85 OO 



Gearing and shafting 15 00 



Material and building of carrier including connections to 



pump and tanli 50 00 



Material for frameworli and putting all the parts together 50 00 



Making a total of $228 00 



A triplex bronze pump can be made to order for $40.00 addi- 

 tional. We believe that the actual cost of building can be re- 

 duced to $200.00. 



CONCLUSIONS. 



When completed and tested the machine proved much less 

 unwieldy and awkward than appearances would indicate. It 

 could be turned in a space of six feet, not including team. All 

 the joints were easily packed to prevent leaking, and, the raising 

 and lowering of the carrier in turning did not cause the hori- 

 zontal telescoping joints to leak. It was thought that it would 

 be impossible to use it in asparagus fields that were on sand 

 beds, nevertheless a span of fourteen hundred pound horses 

 handled it v*^ith but little extra effort on level ground where 

 the wheels sank four inches into the sand. 



Tests showed that an acre could be sprayed in less than an 

 hour, doing the work more thoroughly than could be done by 

 hand. Furthermore, there was a saving of material, as between 

 150 and 175 gals, was all that was used per acre when all the
