Each shade was 4 feet wide and was slightly inclined, resting about 2 feet above the beds on the south side and 2\ feet above them on the north side. The beds had the long dimension east and west and were closed by boards on the sides and on the ends. The diagram (fig. 1) shows the arrangement, and the general appearance of the beds is shown in Plate I, figure 1.
