- The telegram
- A French telegram form (Mexico no. 78, “Mots 98”, Via Anglo, Paris stamp 26 August 1899) from Roberto Núñez, under-secretary of Finance, to the minister José Y. Limantour at 16 avenue Friedland, Paris; 114 units, 65 of them code words.
- Where
- CEHM-Carso, Mexico City, Fondo CDLIV (Colección José Y. Limantour), CDLIV.1a.1883.38.9926, five images. Not on DECODE. Part of catalogue entry 1461; its 1905 items are not read here.
- The cipher
- A word code: only some words are coded, in Spanish dictionary words that keep Spanish endings (jirpeo = indicó, jirpee = indique); the rest is clear Spanish.
- How it was read
- The archive’s record says “sin traducción”, but a contemporary translation is filed as the next two numbers (9927, a pencil draft, and 9928, a fair copy). It gives 36 code values (36 of the 65 code tokens; with the hole ampida, 37 tokens have no value from the key); a key frozen from other telegrams of the same code, each with its plain text, gives 28 more and agrees with the translation in every one.
- What it says
- The President has agreed a loan of 4 millions from the Banco de Londres; surplus funds are to go in gold to the Bank of England; Camacho asks to have the new bonds printed in the United States, which the President fears could draw an injunction against Morgan.
- Still open
- One code word (ampida) is blank in the translation too; two telegraphed words (te se) have no counterpart; five words are supplied by the translator. Counting those, 93.3% of words read, under the 95% bar. 36 code values rest on one source (the 37th token, ampida, is the hole). Frozen before the comparison by the contributor’s record.
- Credit
- Transcription, the finding of the translation, the frozen key and the reading by WAINUT with AI language-model agents, from the CEHM images; the translation is the work of the time. The project re-ran the held-out test and compared the first lines with the scan.
01 The telegram
The record (CEHM ficha 148376) calls the item “Texto codificado. Sin traducción”, which is true of that record. But the file holds the translation under the next two numbers, CDLIV.1a.1883.38.9927 (a pencil draft on Elysée-Palace-Hotel telegram paper, two images) and 9928 (a fair copy headed “Traducción”, signed Núñez, one image). Their text follows the code telegram word for word, so they are the translation of 9926 and not of another telegram. The same code was used by Núñez and Limantour in August 1899 (9922, 9926, 9929, 9930); it is not the Speyer & Co. code of 1905.

02 The code
Code words keep Spanish endings (impulsarlo = hacerlo, impulsése = hágase, intitular = imprimir, besarsele = abonársele); one value can take two code words (garlopas abocados = E.U.); most figures go in clear (23 13/16, 24), but “4 millones” and “2 y 1/4” are coded. No codebook was found in the file: the key is rebuilt from glossed telegrams.
03 The test
The frozen key (90 entries; the file has 97 lines, of which 6 are comments and 1 is the header row) was built first from three other telegrams of the same code, each with its plain text on the same sheet: 9922 (Núñez, 10 August, code and translation), 9929 (Limantour’s draft of 28 August with plain and code words line by line, his answer to this telegram) and 9930 (Núñez, 31 August, code and “Traducción”). It covers 28 of the 65 code-word tokens of 9926 (19 distinct code words; 23 tokens by the same code word, 5 by the same code root with another ending), and all 28 give the value that the contemporary translation gives at the same place. The other 37 tokens are code words that do not occur in the three sources.
That test does not use the translation of 9926, so it is independent of the source of the other 36 values. That the key was frozen before 9926 was compared with the translation rests on the contributor’s record (the file header; one commit, no outside timestamp). The 36 other values come only from aligning the telegram with its translation, token by token, so they have no second source.
04 The reading
Presidente acordó préstamo Banco {de} Londres 4 millones. Pasado año, cuando Gobierno disponga libremente depósitos, Banco abonará 2 y 1/4.

Sírvase resolver. Núñez
Braces mark words the translator added; the square brackets a guess. In English: the President has agreed a loan of 4 millions from the Bank of London; a year hence, when the Government can freely dispose of the deposits, the Bank will pay 2 and a quarter. The President agrees that an amount Limantour is to name from the surplus funds be [placed] in gold in the Bank of England, exchange today 23 13/16; we think that at 24 or more cash could be turned into gold here and sent to Camacho for safekeeping at the English bank, but in any case Limantour is to name the most suitable way. Camacho asks leave to print the new loan’s bonds in the United States; the President draws attention to the possibility that, the bonds being unfinished and unsigned, something like an injunction against Morgan could cause difficulty. Please decide. Limantour’s answer of 28 August (9929) takes up exactly these points. That Camacho is the financial agent and the bonds those of the 1899 conversion is background that the telegram does not give and that was not checked here.
Counted by the README rule: 114 telegram units (43 clear words, 4 clear numbers, 28 code words valued by the frozen key, 36 valued only by the translation, one guess and two words not rendered) plus the 5 words the translator supplied make 119. The holes are the guess for ampida, the two words te se that the translation does not render, and the 5 supplied words: 111 of 119, 93.3%. The contributor’s figure, 111 of 114 units (97%), leaves the supplied words out. The sentences read coherently (grade A), but the share is under 95%, so the telegram is read in part.
05 What remains uncertain
- ampida (line 6) is blank in the translation too (“fondos sobrantes se ___ en oro”); the context and Limantour’s answer suggest “depositen” or “inviertan”, marked as a guess (no key).
- te se (line 16): two telegraphed words with no counterpart in the translation, possibly a transmission error.
- Three code words are not certain on the scan: curadela (under the pencil docket), pareciendo.. (ending under the watermark) and torrejones. Two sign doubts from the second reader: serian may begin with a v and rolliza may end in o; neither changes the reading.
- pasado año is rendered literally as “after a year” (a year having passed); “next year” is possible.
- Thirty-six code values rest on one contemporary translation, with no second source and no codebook in the file. Other August 1899 telegrams of file 38 may share the code (9906-9908, 9923); images of 9906-9908 were fetched but not used.
- The scan was compared again at the integration only for the first three lines; a second reader had read 17 of the 22 lines from the scans before opening the transcription.
- Prior art: the catalogue entry and the record say “sin traducción” and name neither 9927 nor 9928; a web search found general work on the 1899 conversion loan but no edition of this telegram.

Núñez to Limantour, 26 Aug 1899: loan of the Banco de Londres, Bank of England deposit, printing of the bonds in the U.S. read in part
The President has agreed a loan of 4 millions from the Banco de Londres, paying 2 1/4 on deposits once the Government can dispose of them freely; surplus funds, in an amount Limantour is to name, are to go in gold to the Bank of England (exchange today 23 13/16; at 24 or more cash could be converted here into gold and sent to Camacho to be kept at the English bank), Limantour to say how; Camacho asks authority to have the bonds of the new loan printed in the U.S.; the President asks whether unfinished, unsigned bonds in the U.S. might lead to something like an injunction against Morgan. Please decide.
Builds coherent sentences, but under the read bar of 95% of words read as sense (93% here); the holes are marked in the reading.

# Translation of CEHM CDLIV.1a.1883.38.9926 (Roberto Núñez to J. Y. Limantour, Mexico, 26 Aug 1899) English, with the same hole as the Spanish reading (`[?deposited]` stands for the code word *ampida*, which the contemporary translator also left blank). Two telegraphed words (*te se*, line 16) are not rendered, as in the contemporary translation. The President has agreed [to] a loan [from the] Bank of London [of] 4 millions. After a year (*pasado año*, literally "a year having passed"), when the Government freely disposes of [its] deposits, the Bank will pay 2 1/4 [per cent interest]. The President agrees that the amount of surplus funds that you indicate be [?deposited] in gold [at the] Bank of England, exchange rate today 23 13/16. We believe that at 24 or more it could gradually be converted here from cash into gold and sent to Camacho for its safe keeping [at the] English Bank; but in any case you will indicate the most convenient way to handle that position. Camacho asks authorization [for the] bonds [of the] new [loan to] be printed in the U.S. The President calls your attention [to whether], even though the bonds would not be finished, lacking signatures, [in the] U.S., a proceeding similar to a precautionary injunction (*providencia precautoria*) could be brought against Morgan, causing us some obstruction. Please decide. Núñez
