In 1850 young Scottish tree-hunter John Jeffrey is dispatched by an elite group of Victorian subscribers to seek highly-prized exotic tree species in North America. An early letter home tells of a 1200 mile transcontinental journey on foot. Later, tantalising botanical samples arrive from British Columbia, Oregon and California, yet early promise soon withers. Three years after setting out John Jeffrey disappears without a trace. Was he lost to love, violence or the Gold Rush?

The secrets of the extraordinary adventure lie in his precious journals which remained lost, until their discovery, 160 years later. Green Gold is a fictional biography based on a true story told by Gabriel Hemery, a contemporary tree-hunter, forest scientist and author of award-winning The New Sylva.

  • Journal: Shasta Valley, California, 25th October 1852

    I remember there was an unusually big sky that evening, and it was lonely of clouds—surely forewarning a sharp night. I raised a modest fire and added an extra layer of springy branches under my bedroll as a spectacular red sun descended between two giant boulders before me. Thus prepared I drifted to sleep, lying with some satisfaction beneath the canopy of another fine specimen of the magnificent new pine I had discovered days before (No.731). A myriad of stars flickered between the long needles on its gently swaying branches. I was reminded of Humboldt’s analogy—of the blooming, fecundity and withering of stars and planets—and the form of the great garden of the universe which now lay open before me. God had revealed his infinite mysteries.

    Sometime later, while wrapped tightly in a meagre HBC blanket, my hat drawn deep down over my head, such was the cold, I was woken by a great weight upon my chest. It has been more than one month since I last enjoyed close human comfort, and I was confused, before becoming immediately alert.

    Yet, before I could much react, a terrible pain lanced my cheek, and I found my face to be held in a foul stinking vice. Despite finding myself quite blind, and with one arm caught under my blanket, with the other I managed to strike out. My bare hand encountered solid fur-clad muscle. So short was the coat of my foe, there was no handhold. I thought then that I was confronted, not by a Grizzly, but most likely a Mountain Lion. I raised my legs to grapple with its body and rolled over to one side. I felt the flesh on my face tear open, even as I felt for my gun. With the stock I aimed a blow blindly at its body and, on making satisfying contact, felt its jaws loosen. Yet still it did not retreat, its claws holding fast to my body. I fought viciously, with every limb and ounce of my strength, for what seemed many minutes, but must have been mere seconds, before it fled. By the time I had torn the remains of the hat off my head, I managed to glimpse only its long tail disappearing between the same two boulders where the sun had earlier retreated. Yet there it paused to turn and stare. I feared for a moment it was to return, its unblinking eyes reflecting two startling full moons, yet it evidently decided that discretion was the better part of valour. With a turn of its head it was eclipsed by the night.

    I immediately sought to rekindle the fire which had faded to a pitiful glow. With my knife now permanently in one hand, which trembled terribly and quite without control, I heated water to tend to my face and other injuries. I slept for none of the remainder of the night, gripped I admit by terror, and suffering a most fearsome throbbing pain.

    Naturally, I have no glass with me, so I was obliged to wait until the sun had risen before I could inspect my face on the surface of a pool in the creek. Being without the excitement of a fight to mask the pain, applying the crude stitches to my cheek hurt more than the beast’s canines.

    After attending to my wounds I believe that I became quite delirious. I woke many times to find myself surprised that it was day rather than night, or visa versa. My body was often drenched with sweat, and I found myself shivering, even at noon while the sun was at its zenith. My fire, however, I kept burning day and night, even though the usually simple act of gathering kindling and logs was a great burden, on account of the pain.

    I write now, I believe, some two days after the attack. It is unusual for me to stay more than one night in the same place, but I have felt little able to do much more than rest and attend to the fire. While my symptoms were at their height, I experienced vivid and hallucinatory dreams. In many of these I found myself with Prof Woody, and other noble gentlemen, among extraordinary variations of the Edinburgh gardens. What would they think now of my sorry situation? If they could witness my immediate circumstances they would surely experience a similar sense of bewilderment, yet their vision would be no dream. I am a battered man, with a grizzly face, which surely masks completely the youth they despatched with such optimism but two years ago.


    I recall Mr Anderson explaining the habits of the various beasts which might prove a threat to us. I have encountered many Bears, both Black and Grizzly, during my travels thus far, and shot more than I can now remember. In fact, meetings are commonplace with these giants, and it is second nature to take measures to counter their curiosity when establishing an encampment. Yet, I can recall seeing only two Mountain Lions in all my time traversing across this vast country (the last one about one month past). On both of these occasions they have been some distance away. I was well-informed that a Mountain Lion will only rarely attack a man—a child being much more common fare—unless it is surprised, or if that man is a coward who presents a fleeing back. I will remember to inform my old guide of these experiences, if we are fortunate to meet again.

    Earlier, I followed the path that the animal took between the boulders, and just beyond them, along the banks of the stream in the soft mud among its rushes, I found several footprints. Each was the size of the back of my hand. The rear of the main pads had three lobes; a feature I have not seen before. It may confirm my suspicion as to the beast’s identity.


    I have determined that I will start back northwards tomorrow, and to find company as soon as possible in case my wounds fester, although I now feel a little more myself. The snow-clad peak of Mount Shasta exerts a dominant presence in this place, its foothills providing fertile hunting grounds for the botanist. Before me tall pines, all of the same new species that I found these days past, grow between massive boulders, extending without interruption down the valley, and far into the distance. This land is a paradise so rich it would see the same gentlemen emptying their purses to secure more collectors. Yet their ambitions might be cruelly shattered by my appearance.

    I inadvertently started this entry on the inside of the cover and front end paper, of this, my third journal, which is already half-filled. I am usually so diligent about my record keeping. I hope the spattering of blood and other marks across the page will be forgiven. At least the hand with which I write is mostly undamaged; I cannot say the same for my other.

    I'm delighted to see my first book with Unbound Publishing launched.

    It's taken two years of research and writing, interupted frequently by a busy day job, to reach this day yet I've enjoyed writing the story more than I ever imagined.

    They say truth is stranger than fiction, and in the case of the true story of John Jeffrey I've learnt it's even more extraordinary too.
