used in these little experiments. One salt, almost 

 before you are ready, crystallizes into a brilliantly 

 colored, sword-shaped form that darts quickly across 

 the field. Others follow but they never bump into 

 each other. They always stop nearby, and buds or 

 branches begin at once to shoot out from their sides. 

 Soon the whole solution is visible in a delicately 

 woven, gorgeously tinted, beautifully spun design 

 of some royal goldsmith's creation. They grow and 

 grow in breadth, depth, and width, but remain in 

 perfect proportions of naturally carved and many 

 colored filigree work. 



Any amateur chemist may go beyond the mi- 

 croscopic size of these little crystals, and produce 

 vertiable Gargantuan examples. If chromate of iron 

 or cobalt salts are dissolved in pure water and placed 

 in a dark place for some hours, beautiful garnet cry- 

 stals with jewel like facets will be born in the mother 

 liquor, and daughter crystals will be seen budding and 

 growing from the larger ones. These may become so 

 large that they can be exhibited in a show case. It 

 requires no great chemical skill to obtain them. Let 

 any boy or girl that dabbles in elementary chemistry 

 try this, and the reward of success will quickly 

 crown your efforts.

The field is unlimited and uncrowded; marketing the 

 product in competition with the clay interests and at clay 

 tile prices produces a great profit and a glance at the future 

 spells only success for the factory or business started today. 



No existing proposition offers such flattering induce- 

 ments or such a field of opportunity for the man looking 

 for a vocation or for the man looking for an investment. 

 No other business can net you such profits on the amount 

 of capital involved, and no other business has such an 

 unlimited future. 



Just think of a business paying from 30% to 50% on 

 the investment the very first season, and subsequently ' 

 from 50% to 150%, then ask yourself the question Is it 

 worthy of investigation? 



Our literature gives you all the details regarding the 

 merits of cement tile, the cost of manufacture, the amount 

 of capital required to embark in the business; how to 

 build your factory and last, but not least, it tells you 

 how we aid the manufacturer using our machinery and 

 gives you our full and complete proposition. A short 

 letter telling that you are interested will bring complete 

 data.

Is the Best 



INDEPENDENT irrigating sys- 

 tems, when properly operated, 

 prove true to their title they 

 make you independent of rain or 

 other uncertain sources of supply. 

 Almost without exception they prove 

 the cheapest and most satisfactory. 

 If you are able to secure a sufficient 

 supply of water by sinking wells, or from a lake or stream, you should start today to lay out a good irrigat- 

 ing system. Dependable power is easy to obtain. An 



I H C Oil and Gas Engine ; 



will take care of the pumping and will also furnish power to run any farm machine. It will require no watch- 

 ing except to keep it properly oiled. It is the cheapest and most dependable power you can secure. 



I H C engines are built in many styles vertical, horizontal, portable, skidded, air-cooled, water-cooled; in 

 sizes from 1 to 50-horse power. They operate on gas, gasoline, naphtha, kerosene, distillate, alcohol. 

 I H C tractors are built in sizes from 12 to 60-horse power. There are also spraying, pumping, 



hay baling, wood-sawing, outfits, etc.
