prevalent or hard winds, with any slope the ground may have, and 

 its height above the sea should be stated, specifying if possible, the 

 general temperature of the locality, and the degrees of greatest heat 

 gj^nd cold annually experienced. 



With respect to specimens of sub-soils, if of marl, sand, or clay, 

 portions weighing about a pound, should be dried, tied up in a canvas 

 bag, and labelled, to correspond with the respective soils above them. 

 If the subjacent rocks be hard, a piece weighing also a pound, and 

 fresh broken from the body of the rock, as nearly as possible beneath 

 the spot whence any specimen of soil may have been selected, would 

 suffice, and should be wrapped in strong brown paper, labelled to 

 correspond with the soil above it. As specimens of many sub-soils 

 may be rendered valuable for the purpose of illustrating those either 

 well or ill suited to the growth of such trees as by their roots pe- 

 netrate beneath the upper soil, commonly known as vegetable mould 

 or humus, and which upper soil supports the great bulk of the plants 

 commonly cultivated ; it would be desirable to add a memorandum 

 to any specimens which may serve to illustrate points of that kind. 

 All specimens of soils should, if possible, be enveloped in wax cloth, 

 and even packed in tin cases or cannisters, if any are at hand. 



When a sufficient number of specimens in either of the departments 

 here mentioned, has been collected, they should be packed in a box, and 

 be sent by the cheapest, most efficient, and safe conveyance, directed — 



On Service.
