till it makes Right-Angles with thefe three ftakes,and fet up two flakes at each fide one Level with thofe three : So have you five flakes fet true Level in two Lines; and if your Ground be large, you may fet up two Rows more by the Level, but in final! Grounds 5 flakes are enough. Then may you lay by your Le¬ vel, and looking over the head of one to the head of another, caufe your Afliftant to put down flakes be* tween two and two, till you have fet as many flakes level in your Ground as you think convenient : Or you may have a Rule, and look over the edge of that, it being level with the head of the flake, to the head, of the other; and put flakes down between you and the other flake, what Number you pleafe. Thus having flaked out your Ground with all the flakes heads level, and half a foot higher than the higheft part of ybur Ground; in fome Ground the middle-flake, and the flakes in the Crofs-line will be the Level-line the Ground muft be brought to; that is, abating the Hill, and filling up the low-fiae to the Level of the Mid-line : but if your Ground be very uneven, then you muft meafure over all the flakes, and take them middle-high, for their mean Level, and by the Rule of Three proportion your Ground to that. Suppofe a Valley be io Poles long, and 2 Feet deep from the flrait Line, and there is a Hill 5 Poles long, how many Feet deep muft I go in thofe $ Poles of the Hill, to fill up this Valley ? This may be anfwered by the Rule of Three Inverfe, or back Rule of Three: The Rule orders it felf thus. As 5 is to 2, fo is 10 to 4 : fo if you work it by the Line of Numbers, ex¬ tend your Corapafifes from 5 to 2, that fame Extent will reach from 10 to 4; fo then you muff go 4 Feet deep in fuch a Hill, to make good fuch a Valley as is before faid. Suppofe you are to abutt the top of a Hill 4Fe%£ deep, and 1. 2 Pole from the top of that Hill thofe 4 Feet ate to come out ; this is eafiiy performed, (tho a
