Two notebooks contained in dark-blue morocco-covered slipcase, gilded on the spine with the designation  RUSKIN / MS. / POETRY / OF / ARCHITECTURE / MODERN / PAINTERS. / VOL. I. / &C. / 1902. 
	As described in Works 1:2, two identical notebooks contain the incompletely surviving manuscript of The Poetry of Architecture, the series of essays originally published in ?? Loudon’s magazine, ??. The second of the two notebooks contains also manuscript of Ruskin’s letter to the Times of 7 January 1847 (Works 12: 397-406), and early draft of the opening of Modern Painters I (first printed in part, in a heavily edited version, in Works 3: 680-82). The texts are written in ink on lightly ruled, unwatermarked paper, bound in half-calf and marbled boards, approx. 16.8 × 20.3 cm. The binding appears original, as the marbling on the boards matches that on the edges of the paper. The following detailed discussion is focused especially on The Poetry of Architecture. For discussion of the other two manuscripts, see the appropriate volumes in Works and....
	Notebook 1.--The first volume contains 64 leaves, including endpapers. The text begins on 3r, and is accurately numbered by Ruskin as pp. 1-122 (page numbers are frequently omitted, but the next page to be numbered is always counted accurately, as if all pages had numbered consistently throughout). Although this notebook contains fewer leaves than does notebook 2, it shows no evidence of leaves having been removed.
	Tipped into the front of the notebook 1 is a description, in Wedderburn’s hand, listing the contents as follows:

Ruskin MS.
This book contains the original MS. of the following chapters of  The Poetry of Architecture 
Part I.	Chap.	3.
4.
5.
6.
Part II.	Chap.	1.
2.
3.
4.
5.
	Wedderburn’s table accurately lists the contents, according to the chapter’s numbering first adopted in ? and carried through ?. Notebook 1 begins with what Ruskin designates in manuscript as  No. 4,  a chapter found as chapter 3 in the Library Edition. This discrepancy carries through the draft’s  Chap. 7th --that is, chapter 6 of part 1 in the Library Edition--and on into the draft’s  Ch. 8. The Villa,  which forms chapter 1 of part 2 in the Library Edition. Notebook 1 continues in this manner through  Chap 12. <No 3.> The Villa. --that is, in the Library Edition numbering, chapter 5 of part 2.
	Notebook 1 contains the originals of a few, by no means all, of the diagrams and sketches used to illustrate the published papers. One pencil sketch on the back endpaper of a roofline with gothic arches is not published, so far as I am aware.
	Notebook 2.--This notebook is second in the sense that it contains the continuation of the Poetry of Architecture essays from notebook 1. Notebook 2 nonetheless displays a large, handwritten numeral  1  on the front cover. If by Ruskin, the numeral perhaps refers to the Modern Painters manuscript, which was begun on a recto immediately following the Poetry of Architecture the last installment of the manuscript.
	Notebook 2 consists of 83 leaves, including some that have been partially cut away. A few more leaves were cut away altogether, with only very small stubs left behind.
	Wedderburn’s table of contents, tipped into the front of notebook 2, reads as follows:
Ruskin MS.
This book contains
1.	Chapter VII of Part II of the Poetry of Architecture--arranged in the MS as two chapters 14 & 15.
2.	MS. of parts of Modern Painters. Vol. 1.
3.	The draft of the letter on the  National Gallery  (Times Jan 7, 1847), p. 38
	The major portion of The Poetry of Architecture contained in the second notebook is chapter 7 of part 2, the final chapter published by Loudon before ceasing publication of his magazine. In draft, this chapter is divided in two, designated as chapters 14 and 15. The division occurs at paragraph 230 as presently numbered, this paragraph forming the opening of the draft chapter 15. Since the two draft chapters are entitled identically in draft, as  The mountain Villa. England,  Ruskin must always have conceived of them as a unit.
	Wedderburn’s table of contents for notebook 2 fails to list a portion of what is now known as chapter 6. Wedderburn may well have overlooked the chapter 6 fragment, since these few paragraphs follow chapter 7 in manuscript, and are not separately headed--only a blank line space indicating the separation between chapters. Wedderburn’s omission is corrected in the description of the manuscript provided in the Library Edition (Works 1:2), but this description, while generally accurate, allows the impression that the first notebook ends with the fragment of chapter 6--that is, with paragraphs 182-84, as numbered in the Library Edition--whereas, in fact, notebook 1 ends with paragraph 181 (Works 1:138), the conclusion of chapter 5, part 2. Paragraphs 182-84 constitute the fragment of chapter 6 that follows chapter 7 in notebook 2.
	 More precisely, the fragment of chapter 6 in notebook 2 extends from its opening (paragraph 182) through the middle of paragraph 184, ending with the phrase  fine detached specimens of the picturesque blue country  (in the published version,  fine detached specimens of the natural ‘green country’  [Works 1:140]). According to the Library Edition, this opening of chapter 6 plus a few more paragraphs existed also in a separate manuscript:  §§ 182-194 are preserved in the four pages of a separate sheet of foolscap. Thus of §§ 182-184 there are two MS. copies  (Works 1:2). This second foolscap copy must have been what was reproduced for the Library Edition (Works 1:140 opp.), since that facsimile shows a portion of manuscript later in paragraph 184 than what is available in notebook 2. The foolscap manuscript is not held by PML....
	As for the remainder of The Poetry of Architecture manuscript, not contained in the PML notebooks or the ? foolscap manuscript, the Library Edition’s statement apparently remains correct, that  of §§ 1-37 and §§ 194-212 there is no MS extant  (Works 1:2).
	In notebook 2, the text begins on 3r, and, as in notebook 1, the pages are accurately but erratically numbered by Ruskin--i.e., he counts the pages correctly, but actually writes numbers on the pages sporadically, starting from page 7. This continues through page 34; pages 35-36 (unnumbered by Ruskin) hold the end of chapter 7, and the fragment of chapter 6. Then begin the later manuscripts included in notebook 2, the Times letter (Works 12:397-406), and the Modern Painters I fragment.
