It is not necessary that they should be in precisely the quantities named here, but they must all be present. The proportions of some of these may seem so small as to be unimportant; that they are not, will ap- pear when we consider how many hundred pounds there are in an acre of soil twelve inches deep. The smallest of the above proportions would, for an acre, amount to several tons. It would require an im- mensely heavy manuring to add one half of a per cent of any particular ingredient to th...e soil. Unfortunately soils of the first class are not so plenty as those of the second, which bear good crops if an abundance of manure is added. Such are our ordinary soils in all parts of the country. It will be seen that in the column representing the composition of this soil, there are blanks opposite to the potash, soda, and chlorine, denoting that these are absent. Several others, sulphuric and phosphoric acids, and lime, are in much smaller quantities than in the first column. In the third column, we find just half of the inor- ganic bodies present in the first entirely wanting, and two others, lime and magnesia, greatly reduced in their proportion.
