Sir

I read with much interest the notice of your remarks on Worms¹

In or about the year 1833 I made an experiment with a view to improve a field of Sandy loam, by a uniform coat of Gault Clay.² Since that time no manure except that from cattle has been put on the field. From time to time I have examined the soil and find a layer of Clay beneath now 3$\frac{1}{2}$ inches with a certain degree of regularity all over the field   I send by this same post enclosed a specimen of the clay dug from the subsoil at 3$\frac{1}{2}$ inches, deep— my Bailiff³ tells me that often in the morning, when he has seen the moles working he has very often seen the worms as in terror escaping to the surface before the movement of the moles under ground— I think these facts may interest you
