What is lacking in the field of practical science, as authoritatively voiced by the unprogressive faculty of today, is an absence of chemical knowledge, especially on the part of the physician and the naturalist; and, as likewise, the so-called scientific farmer upon whose assurances we so naturally rely for the wholesome production of food is woefully ignorant on matters of agricultural chemistry, the logical consequence is that in all civilized countries great mistakes have been unconsciously made and perpetuated, detrimental to the health of man and beast alike and vitally prejudicial to the healthy sustenance of the race. _Where are the most vitally necessary mineral substances_ to be found in nature? It is an established fact that the fields, on which our nutritive salts or cell-foods--our vital sustenance--are grown, were originally formed from decayed primitive rock and _this primitive earth-crust matter is composed of the same mineral substances that are found in normal blood_. Therefore, our physical welfare and our capacity to resist disease is clearly dependent upon the condition of our fields. We must always bear this in mind--the old truism--that, "AS A MAN EATS, SO IS HE." _We are thus, directly, the products of our fields._ Wrongly fertilized, our fields must produce sickly vegetation, and this in turn will produce a sickly race and disease in cattle. Primitive rock consists of granite, porphyry, gneiss and basalt, deposits which are still found upon the earth in immense quantities, and in the same condition as thousands of years ago. As a matter of fact, proposals have been made by noted scientists to utilize pulverized rock of this kind as compost to _assist_ the fields in a natural way, and so to restore them to their former producing power, which would thus enable plants, animals, and man, alike, to regain those substances indispensable to proper sanguification and general growth. The agricultural experiments performed with this stone dust fully confirm this assumption. One of the most important tasks of today is to indicate to the farmer new ways and means of promoting and increasing growth for the food supply of the nations. Why, then, I imagine I can hear it asked, if this fact be true and demonstrated, has it not been applied? This question may be answered by another. Why does not the natural system of Hygienic Dietetic Healing find general application in cases of sickness, since its success is so obviously greater than even that claimed by medical science?
