7. Draw a plan of a small estate, consisting of four fields, and find the respective areas of the different inclosures, and the contents of the whole, from the following dimensions.

NOTE. The field-notes in this Example are entered from the left towards the right; but in all the foregoing Examples, they are entered from the right towards the left. Both methods are consequently exhibited; and, of course, the Learner is at liberty, when he commences field-practice, to follow that of which he most
