CHAPTER 96 · THE TRY-WORKS

Besides her hoisted boats, an American whaler is outwardly distinguished by her try-works. She presents the curious anomaly of the most solid masonry joining with oak and hemp in constituting the completed ship. It is as if from the open field a brick-kiln were transported to her planks.

The try-works are planted between the foremast and mainmast, the most roomy part of the deck. The timbers beneath are of a peculiar strength, fitted to sustain the weight of an almost solid mass of brick and mortar.

It was on a dreary night of November, that I beheld the accomplishment of my toils. With an anxiety that almost amounted to agony, I collected the instruments of life around me, that I might infuse a spark of being into the lifeless thing that lay at my feet.

I had worked hard for nearly two years, for the sole purpose of infusing life into an inanimate body. I had desired it with an ardour that far exceeded moderation; but now that I had finished, the beauty of the dream vanished, and breathless horror and disgust filled my heart.

It may metaphorically be said that natural selection is daily and hourly scrutinising, throughout the world, every variation, even the slightest; rejecting that which is bad, preserving and adding up all that is good; silently and insensibly working, whenever and wherever opportunity offers.

We see nothing of these slow changes in progress, until the hand of time has marked the long lapse of ages.

Chapter I · Ask the book

Ask the book anything, without leaving it.

A question mid-chapter used to mean putting the book down and opening a browser. In Readr you ask on the page. The answer lands in the margin, with citations back to the passages it came from.

HOW TO STOP THE RUMINATIONRumination is like a thoughts washing machine. It's the process of churning thoughts over and over for minutes, hours or days at a time.

"Is there real evidence behind this?"

In the book: Smith cites Watkins & Roberts (2020) on rumination maintaining depression. Beyond it: that work grew into rumination-focused CBT…

P. 179 OF 486In 1970, Baltimore and Temin discovered an enzyme found in retroviruses that could build DNA from an RNA template.

"Is this the enzyme mRNA vaccines use?"

No — reverse transcriptase runs RNA→DNA; mRNA vaccines skip that entirely. Beyond the book: it's what HIV antiretrovirals target…

P. 118 OF 496"See? Spin. Spin drive." … Astrophage thrust is based on strength of IR light. Dim light make weak thrust.

"Could astrophage really exist?"

Nothing biological stores energy at that density — but Weir builds it from real physics: Petrova-frequency IR is…

Answers start from the book you're reading, but they aren't fenced in by it. When a question needs outside knowledge, the model brings it.

Chapter III · Listen

Let the book read to you.

Some evenings you want the book and your eyes are done. Press Listen and Readr reads from the page you're on, not the top of the chapter, turning pages to keep up with the voice. Stop mid-sentence, come back tomorrow, and you're exactly where the voice left off, whether you pick it up by reading or by listening.

Sentence & chapter skip Speed, changed mid-sentence Readr Voice, or any Apple prose voice Sleep timer that counts listening Lock screen & headphones

The voice runs on your device. There's no account and no subscription, just a one-time download of about 104 MB, and an Apple voice reads to you while it arrives. Nothing from your book is sent to a server to be read back to you. It's the one feature here that needs no provider at all.

Chapter IV · Bring your own AI

Sign in with your OpenRouter account, or with ChatGPT on the Mac. Paste an Anthropic or OpenAI key. Or run a local Ollama model on your Mac and stay offline entirely. There's no Readr account and no server in between; the app talks straight to the provider you pick.
