No. 357.
Sir Edward Thornton to Mr. Blaine.

Sir: With reference to my note of the 10th instant relating to the report made by the acting British consul at Philadelphia in December last, I have the honor to inform you that as the statement that 700,000 head of swine had died in Illinois of cholera during the year 1880, had been transmitted by the British vice-consul at Chicago, I instructed Her Majesty’s consul at Philadelphia to request that vice-consul to furnish the data and authority upon which he had founded the statement in question.

I have now the honor to transmit herewith copy of a letter and an accompanying memorandum sent by Mr. Warrack to Captain Clipperton snowing upon what authority the former made the statement which has given rise to so much bitter and even unjust comment.

You are doubtless aware that Her Majesty’s consular officers are in possession of peremptory instructions from Her Majesty’s Government to make periodical reports of the sanitary condition of the domestic animals in this country, so many of which are now contributing towards the supply of food to the inhabitants of Her Majesty’s dominions. In performing this duty they naturally endeavor to obtain the most correct data, and I know not where they are so much justified in looking for them as in the statistics collected by the authorities, whether of individual States or of the United States. In this instance Mr. Warrack appeals to statistics collected and furnished to the agricultural department of Illinois by the assessors of that State, and he shows that the statement which has been the subject of so much complaint is borne out by the figures given by the assessors. It is admitted by the agricultural department of Illinois that the loss of hogs by disease in that State was greater in 1880 than in 1879. The assessors declare that the number of pigs and hogs which died of cholera in 1879 was 676,738. It is therefore probable that Mr. Warrack, in stating that 700,000 had died in 1880, was rather under than over the mark.

It may be that the returns made by the assessors were incorrect, and they are certainly not in accord with those published by the agricultural department of Illinois; but no blame can certainly attach to Mr. Warrack for giving credit to the statements of such officials as the assessors of Illinois.

I have at the same time the honor to invite your attention to the Report of the United States Commissioner of Agriculture for 1879, page 24, where, in speaking of hog cholera, it is stated that— [Page 584]

Careful returns from correspondents of the department show these losses to be at present from $15,000,000 to $20,000,000 annually.

It is added that it is not unusual to receive intelligence from some of the large hog-growing localities in the West that the losses in single counties will reach the large sum of $50,000 to $80,000, and in some instances as high as $150,000 in one season through the devastating operations of this disease.

I have, &c.,

EDW’D THORNTON.

Mr. Warrack to Mr. Clipperton .

Sir: I beg to acknowledge the receipt of your dispatch of the 12th, inclosing copy of one from Sir Edward Thornton to you of the 10th instant, and inquiring as to the basis on which I formed my calculations, &c., when reporting to Mr. Vice-Consul Crump on the mortality among swine in the State of Illinois in the year 1880; and in reply I beg to say that the statement, as forwarded by me to Philadelphia on the 18th of December last, was founded on official documents in my possession, and other data, as more particularly set forth in the inclosed memorandum.

I have, &c.,

J. WARRACK,
British Vice-Consul.

memorandum.

Illinois agricultural department’s circular No. 70, dated August 20, 1880, the latest available at date of my letter of 18th of December, 1880, states the number of hogs and pigs died of “cholera” as follows: 1877, 1,445,268; 1878, 1,391,422; 1879, 676,738.

These are the figures returned by assessors. Years 1878 and 1879 are verified by showing in detail the loss in each county; vide for 1878, page 383 of the seventeenth volume Transactions of Department of Agriculture, Illinois; and for 1879 see page 107 of circular 70. For the year 1878 thirteen counties do not appear to have reported, and there are three missing in 1879. The number of hogs assessed per reports of assessors (see page 50 of circular 70) are, in 1879, 2,799,051; 1880, 3,133,557.

At this date, 20th August, 1880, the percentage of deaths of the assessed hogs in 1880 had not been ascertained, but in circular 72, of 31st of December, 1880, it is given as 6 per cent. in 1879, and 7 per cent. in 1880, and on page 80 of circular 72 the following figures appear:

Year. Number of hogs assessed. Per cent. died. Number died. Average weight. Value.
1877 2,961,366 12 358,844 104 $1,853,415
1878 3,334,920 14 474,758 108 1,438,589
1879 2,799,051 6 182,577 98 588,487
1880 3,133,557 7 227,259 104 937,293

This shows an increase of 12 per cent. in the number of assessed hogs, and a further increase, viz, 1 per cent. in the rate per cent. of those which died. That there were more swine in Illinois in 1880 than in 1879 is corroborated by the following statistics, taken for the regular “Board of Trade” circular, issued daily, from the best and most trustworthy sources accessible to the publishers: [Page 585]

1880. 1879.
* Receipts of hogs at Chicago for ten months, to November 1 5,222,495 4,888,309
Shipments, same period 1,285,993 1,509,840
Number packed, including city consumption from January 1 to November 1, 1880 3,936,502 3,278,469
Number packed from the first of November, 1880, to December 17, 1880, the date of my advice being 18th of December 1,505,050 1,300,000
Total 5,441,502 4,578,469

Increase of hogs killed in Chicago from 1st January to 17th December, 1880, 863,033, or 19 per cent. The increase in the number assessed as reported by the State assessors, being the difference between 2,799,051 for 1879 and 3,133,557, is 334,506, or 12 per cent.

It will be observed that the figures dealt with by the parties interested in attacking the accuracy of Mr. Crump’s report are the deaths of the assessed hogs, and they do not appear in any of their numerous published communications to refer to the figures as given by the only authorized State assessors of Illinois, and published in the Illinois reports of the deaths of the total so-called “hog crop” of the State.

Something has been said by the parties who ignore the total deaths to show that the light weights of the assessed hogs, say an average of 108 pounds in 1878, 98 pounds in 1879, and 104 pounds in 1880, prove these to have been among young “shoats” and pigs; but turning to the reports of the assessors, as detailed on page 81 of circular No. 70, dated 20th August, 1880, we find that the gross weights of the “hogs and pigs which died of cholera” and the number in the following years are as below:

1877. 1878. 1879.
Number of hogs and pigs died of cholera 1,445,268 1,391,422 676,738
Total gross weight of swine died of cholera pounds 106,949,832 139,853,508 49,326,591
These give average weights in these years of do 74 100 73

as against 108 and 98 pounds already quoted as the average weight of the swine which died in these years (1878 and 1879) out of the assessed numbers.

The figure 700,000 given by me was purposely put low, and was based mainly on the statistics as published, and also on the general information one gathers from dealers and farmers. Had the circular of 31st December, 1880, been available at the time I reported, or rather had I reported after its issue instead of before, I would have made the loss at least 750,000, perhaps 800,000; for, if a loss of 182,577 accrues in 1879 from a 6 per cent. rate on 2,799,051 assessed swine, and the total loss in the same year, 676,738, then it is clear that if the death-rate in 1880 is 7 per cent. and the deaths of assessed hogs 227,259 out of 3,133,557, then the total deaths for 1880 of all the swine raised in the State will be about 842,000.
