To J. H. Gilbert [before 9 March 1876]1
Down | Beckenham | Kent
My dear Sir
I thank you most cordially for the great trouble which you have taken in writing to me at such length.2 Your letter is of the greatest value to my son3 & my self & we shall at once order the necessary salts at Messrs Griffin & begin preparing the soil.4
May I ask you two other questions which you could answer very briefly?
(1) Can you tell me to what point the soil should be burnt? I presume that clay burnt to the same amount as bricks (which would be equivalent to powdered brick) could not be properly purified by washing? We thought of making a rough gridiron of iron bars raised from the ground, so as to roast a layer of clay spread on it, by lighting a wood & coal fire under it. Do you think that this method would answer? we have the same kind of soil you mention in the Phil Trans ie clay & flints on chalk5
(2) Would it be advisable to wash the soil once with dilute acid in order to insure its freedom from alkali?
Pray thank Mr Lawes for his very kind message.6
I am sorry to say that I am not strong enough to accept it, but my son would very much like to inspect your plots in May or June. He has hardly sufficient Botanical knowledge; but an examination of your plots would be highly interesting & instructive to him
With very sincere thanks | I am dear Sir | Yours very faithfully | Ch. Darwin
