"'Should the European war be in progress at that time, I direct that you four throw your power on the side of the United States for the defeat of the Central Powers. That you will be able to accomplish that defeat I cannot doubt. "'If, on September 4th, 1923, the United States is formally at peace with the powers of the world, you are forbidden to use these chemicals for any purpose other than joining me in the world of the ring. If any among you wish to make the venture, which I hope may be the case, I request that you do so. "'Among these pages you will find a list of fourteen chemicals to be used by Dr. Frank Adams during the month following September 4, 1923, for the compounding of my powders. Seven of these chemicals (marked A), are employed in the drug used to diminish bodily size. Those seven marked B are for the drug of opposite action. "'You will find here a separate description of each chemical. Nine are well known and fairly common. Dr. Adams will be able to purchase each of them separately without difficulty. Three others will have to be especially compounded and I have so stated in the directions for each of them. Dr. Adams can have them prepared by any large chemical manufacturer; I suggest that he have not more than one of them compounded by the same company. "'The two remaining chemicals must be prepared by Dr. Adams personally. Their preparation, while intricate, demands no complicated or extensive apparatus. I have tried to explain thoroughly the making of these two chemicals, and I believe no insurmountable obstacle will be met in completing them. "'When Dr. Adams has the specified quantities of each of these fourteen chemicals in his possession, he will proceed according to my further directions to compound the two drugs. If he is successful in making these drugs, I direct that he make known to the three other men referred to, the contents of this letter, after first exacting an oath from each that its provisions will be carried out. "'I think it probable that Dr. Adams will succeed in compounding these two drugs. It also seems probable that at that time the United States no longer will be at war. I make the additional assumption that one or more of you gentlemen will desire to join me in the ring. Therefore, you will find herewith memoranda of my first journey into the ring which I have already described to you; I give also the quantities of each drug to be taken at various stages of the trip. These notes will refresh your memory and will assist you in your journey. "'I intend to suggest to Dr. Adams to-day when I hand him this letter, that in the event of my failure to return within a week, he make some adequate provision for guarding the ring in safety. And I must caution you now, before starting to join me, if you conclude to do so, that you continue this provision, so as to make possible your safe return to your own world.
