21 May 1875

Dear Sir

I am much obliged by your courteous letter but beg to be allowed to point out that the passages you quote from Le Couteur make no reference to the difference of grains from the same ear.1 In these very passages he also distinctly states that his object (of obtaining a pure stock) can be attained equally by starting from either single grains or single ears.

At page 17 he speaks of afterwards sowing “only the produce of the most productive” but it relates to the Comparative productiveness of different sorts, not of different plants of the same variety.2

At foot of same page he begins his accounts of his trial of 14 sorts against each other one ear of each.

In your important Work you say that “he found the grains of the same ear differed so that he was obliged to select them separately and each grain transmitted its own character”. and go on to say “The great amount of variability in the plants of the same variety is another interesting principle”3   If you turn to pages 12 and 14 you will see that the ears he collected as of one variety were so merely in appearance, as he afterwards proved.4

Before one can speak of variation of a variety there must be a standard from which to vary—and strictly speaking there was no such safe standard until I established my pedigree cereals—Col le Couteur did not discover “the variability of a pure variety”, or “the different powers of grains of the same ear.—”5

I enclose copy of a short essay I wrote in the Royal Agl. Society’s Journal in 1862 and have marked paragraph on pp 6 & 7 as to my modus operandi.6 In 1860 Col le Couteur sent me his book,7 and in a letter of 15 Octr of that year he says

“I sincerely congratulate you on your success. The great leading principle of my experiments was one which you have so well accomplished—the selection of the most productive wheat from a single grain—originally taken from the finest ear—my further test being to discover, that most productive of the finest meal”.

Here is his own statement 24 years after his book was written—

In fact Col le Couteur’s whole work may be described as trying to find the finest (in quality) and most productive wheat. So entirely did he keep to this simple end and so little did he think of making selections among plants of any one variety—that he incidentally almost “fixed” the ear of his Belle Vue Talavera Wheat of which he sent me two ears, as you will see in a paragraph of my paper read at Exeter.8

Any field of ordinary Wheat would be found by a trained observer to consist of perhaps 20 different varieties.

A neighbour once showed me a field he prided himself on being pure— I stepped a few yards into it and brought him a dozen different ears which he could recognize as of different sorts—

You will see by the extracts from the Press of England Australia, America &c (sent herewith) in the year 1862 that I naturally felt surprise at receiving no mention in so important a work as yours published in 1868 and above all at having what I had discovered attributed to another.9

On the inside I send rough sketch showing my system of selection— and am | Dear Sir, | Yours faithfully | Fredr. F. Hallett

See letter to F. F. Hallett, [19 or 20 May 1875] and n. 3, for CD’s interpretation of John Le Couteur’s practice of choosing seed-grain for his experiments on wheat breeding.
Hallett refers to Le Couteur 1836, p. 17.
See Variation 1: 314.
See Le Couteur 1836, pp. 12 and 14.
Hallett first articulated this discovery in his paper ‘On “pedigree” in wheat as a means of increasing the crop’ (Hallett 1861). By 1860, he had established a lucrative seed business after insisting that growers had to buy new seed from him every year to maintain high yields; he adopted ‘pedigree’ as his trademark (Charnley 2013, pp. 76–7; Stuart F. Elton, ‘Frederick F. Hallett Cereal Seed Bag Seal’, (accessed 25 February 2014)).
Hallett’s article ‘On “pedigree” in wheat’ was published in the Journal of the Royal Agricultural Society of England (Hallett 1861), and later reprinted as a pamphlet (Hallett 1862); CD’s copy of Hallett 1862, marked as Hallett described, is in DAR 200.3: 30.
Hallett had presented a paper at the meeting of the British Association for the Advancement of Science in Exeter in 1868, in which he stated that since 1861 he had cultivated successive crops of Belle Vue Talavera wheat from grains supplied by Le Couteur in 1860. (In CD’s copy of the paper this paragraph is outlined in blue pencil (DAR 200.3: 31).) Over this time Hallett was unable to produce any variation in the number of grains in an ear of Belle Vue Talavera although he had done so in over seventy other varieties he had cultivated, leading him to conclude that Belle Vue Talavera wheat ‘showed an unmistakeable transmission of the characteristics of the parent to its progeny, and its practical fixity of type’ (DAR 200.3: 31).
Hallett had sent CD a copy of his paper on ‘On “pedigree” in wheat’ (Hallett 1861) that had been reprinted in 1862 (Hallett 1862) and bound with notices from various newspapers and periodicals from around the world praising Hallett’s pedigree wheat (see DAR 200.3: 30). CD had not known of Hallett’s work at the time he published Variation in 1868, but he added a reference to it in Variation 2d ed. 1: 332.

Insists that he, not Le Couteur, was the first to recognise and exploit variation within wheat varieties. Disturbed he was not acknowledged in Variation.
