Evidently fairly heavy rain again last night. This morning overcast, the afternoon still, sunny, & fairly warm. This evening rain again, but more like April showers that the previous rain. Saw the first swallow this afternoon (two. The one I saw close to was a swallow, not martin. I usually see sand martins first of all.) This is a little later than usual, but not as much as a week later. Sowed a few more sunflower seeds. Rolled the grass.
