Here is an illustration of ornamental garden fences from A Dictionary of Modern Gardening, 1847.
"The figures 42, 43, 44, illustrate three simple designs, formed by straight slats or pales, and therefore of the least expense; they are readily executed, and agreeable from their simplicity. The colour which should be used, is of course a matter of taste; white is generally preferred, though dark shades, even jet black are the most pleasing to many."
I personally like the center one, painted white, for it's simplicity and ease of instillation.
It is interesting that the book also mentions a reference to a fence law passed in Pennsylvania in the 1700s stating that "all cornfields and grounds kept for inclosures within the said province and counties annexed shall be well fenced with fence at least five feet high and close at the bottom". Living in said province, I can personally attest to the need for such a fence especially around the corn as well as tomatoes, peas, lettuce, squash and anything else that you want to grow. Without a fence as described, you will loose all that you have planted to the deer. The need to make a law concerning this is a bit baffling however. By 1728, the book tell us, that the law had been amended to state that the fence only had to be 4 foot tall and could be off the ground as much as 9 inches but no more.
