Thiselton-Dyer has asked on CD’s behalf for results of experiments at Rothamsted on herbage of permanent meadow land. Sends report and tables of botanical analysis.

Discusses fairy rings.

Thanks for a copy of Insectivorous Plants.

Discusses in detail how to prepare for experimental purposes a soil that lacks nutrients.

Sends advice on preparing and washing soil in preparation for CD’s experiments.

On burnt soils.

The laboratory has scarcely any experimental evidence on acidity of humus soil and earthworm excreta. Refers CD to some sources of information.

Sends some books.

Invites CD to visit Rothamsted. The experimental plots are at their best "as illustrating the vast influence of external conditions on the character and results of the struggle between the numerous components of an established mixed herbage".

Thanks CD for Earthworms.

Discusses the problem of accounting for difference between nitrogen in permanent grassland and ordinary arable soil. Finds castings of earthworms rich in nitrogen. Asks CD if his observations enable him to explain the source. If from below top-soil, it would be a considerable manuring.
