Destiny of the Republic - By Candice Millard Page 0,93

continued to worsen, Bliss began to panic. Finally, at noon on July 26, he sat down and wrote a letter to the inventor, avoiding, as had Bell, the telegraph station. “Will you do us the favor to call at the Executive Mansion at about 5 p.m. today and work the experiment with the Induction Balance on the person of the President?” he wrote in an elegant, slanting hand on White House stationery. “We would be glad to have the experiment tried at the time of the dressing changing, about six p.m.”

That morning, Bell had slept until eleven. He felt “tired, ill, dispirited and headachy,” and had crawled into bed the night before “thoroughly exhausted from several days of hard labour.” He was still hunched over his breakfast when Tainter arrived, carrying Bliss’s letter, which had been sent to the laboratory by White House courier. As he held the letter in his hands, Bell regarded it with a mingled sense of excitement and fear. “Our last opportunity for improving the apparatus had come!” he would write Mabel later that night. Throwing on some clothes, he rushed to the laboratory with Tainter at his side and immediately set to work. He had one objective in mind: improving the induction balance’s hearing range, so that it could detect an even deeper-seated bullet.

The day before, Professor Henry Rowland, who occupied the chair of physics at Johns Hopkins University in Baltimore, had visited Bell to make a suggestion. If Bell added a condenser, which can store and quickly release an electric charge, to the induction balance’s primary circuit, he could increase the current’s rate of change, and probably obtain a clearer sound. Bell didn’t have a condenser and didn’t have time to find one. That morning, however, in a moment of inspiration, he suddenly remembered that, when returning from his last trip to England, he had brought with him a large induction coil. Inside the coil was a condenser.

Breaking open the instrument, Bell removed the condenser, attached it to his invention, and was thrilled with what he found. Not only did it improve the sound, it increased the induction balance’s range. Bell could now detect a bullet nearly three inches deep in the president’s back. That, he hoped, would be enough.

As he left the laboratory, Bell made a rare stop at the telegraph station. Deciding to try his hand at subterfuge, he wrote to Mabel that the “trial of the apparatus on [the] President” would not take place for several days. The telegram, he later told her, was “intended not for you at all—but for the employees of the Telegraph Company.”

A few hours later, Bell and Tainter arrived at the White House. Between them, they carried the newly improved induction balance, with all of its many parts and a tangle of wires. Approaching the house, they headed not for the front door, where they would risk being seen by the crowds of people still camped out in the park across the street, but to a private entrance in the back.

Bell was uncomfortably aware that the president had expressed reservations about this test. “Mr. Garfield himself is reported to have said that he was much obliged, but did not care to offer himself to be experimented on,” Mabel had written to her mother a week earlier. “Of course not, but Alec isn’t going to experiment upon him.” The test, however, was an experiment. Bell’s invention was less than a month old and had undergone significant changes only that afternoon. He had tested it, moreover, on only one other person, a man who had been perfectly well for many years.

After being quickly ushered inside, Bell and Tainter were shown up the narrow servants’ staircase to the president’s room. When Bell walked in the door, he was astonished by what he saw. The president lay sleeping, a peaceful expression on his face. He looked “so calm and grand,” Bell later wrote Mabel, “he reminded me of a Greek hero chiselled in marble.” Garfield, however, bore little resemblance to the man Bell had seen so many times before in pictures and paintings, always with the appearance of vibrant health—“the look of a man who was accustomed to work in the open air.” The man before him now was an “ashen gray colour,” Bell wrote, “which makes one feel for a moment that you are not looking upon a living man. It made my heart bleed to look at him and think of all he must have suffered to bring
