Actually, with the article is a diagram of the piping.
This one used perferated pipe. I have also seen dispersion heads that look like giant shower heads.
TEP-I can e-mail you the entire article if you want. It includes photos and drawings.
Here is more of the text.
In excavating for the greens the clay subsoil was removed to a depth
of 12 inches and the tile laid in grooves cut with a long hand-trowel. In
the light, of developments since that time it is agreed that there are un-doubted advantages in a deeper bed, and in any new construction the beds would be excavated to a depth of 20 inches or more. In the laying of the tile in the Country Club greens 6-inch pipe was used to form the main line, with 4-inch tile laid as laterals. In some of the greens, the system took the form of a continuous one, winding its way back and forth in sinuous fashion, from the inlet to the outlet valve. As to the respectivemerits of these methods, an examination of the greens fails to reveal any advantage in the one over the other; yet as a practical proposition the effects of stoppage in the continuous system might involve more serious consequences than in the other.
After the layingof the tiles in grooves at the bottom of the excavations,
they were covered with coarse cinders, Sorming a layer of 6 or 7 inches, in the nature of an auxiliary to the drainage system. Cinders were adopted in perference to sand because it was felt that they would stay in place and hold the tile in surer alignment. In addition, the merits of cinders had been proclaimed as a means of obviating the earthworm problem.
This latter supposition has not proved correct in our experience, although the worm problem has never reached serious porportions on our course.
On top of the cinders a layer of earth was placed varying in depth
from 3 to 4 inches. On top of this the seed bed of about 2 inches in depth was formed, consisting of a mixture of sand, earth, muck, humus, manure and some lime.
