"Ah, miss," retorted the man, his eyes twinkling, "you could start the prettiest shindy you ever saw by getting all the gardeners in Ireland together, and asking them to decide which was the true shamrock!"
I suppose I may as well thresh out the question here, so far as it is possible to thresh it out at all, for though, in the east, the west, the north and south of Ireland, we sought the true shamrock, we were no more certain of it when we got through than before we began. The only conclusion we could reach, after listening to every one, was that there are three or four varieties of the shamrock, and that almost any trefoil will do.
The legend is that, about 450, St. Patrick reached the Rock of Cashel, in his missionary journeyings over Ireland, and at once went to work to convert Ængus MacNatfraich, the ruling king who lived in the great castle there. One day, out on the summit of the rock, as the Saint was preaching to the king and his assembled household, he started to explain the idea of the Trinity, and found, as many have done since, that it was rather difficult to do. Casting about for an illustration, his eyes fell upon a trefoil growing at his feet, and he stooped and plucked it, and used its three petals growing from one stem as a symbol of the Three-in-One. This simple and homely illustration made the idea intelligible, and whenever after that St. Patrick found himself on the subject of the Trinity, he always stooped and plucked a trefoil to demonstrate what he meant.
Now of course the true shamrock is the particular trefoil which St. Patrick plucked first on the Rock of Cashel, but there is no way of telling which that was. In his subsequent preaching, the Saint would pluck the first that came to hand, since any of them would answer his purpose, and so, sooner or later, all the Irish trefoils would be thus used by him. The Irish word "seamrog" means simply a trefoil, and in modern times, the name has been applied to watercress, to wood-sorrel, and to both yellow and white clover; but nowadays only the two last-named kinds are generally worn on St. Patrick's day. Whether white or yellow clover is worn is said to depend somewhat on the locality, but the weight of authority is, I think, slightly on the side of the yellow.
Whatever its colour, it is a most elusive plant and difficult to get. Our original idea was that every Irish field was thick with shamrocks, but in no instance except that of the gardener at Clondalkin, do I remember any one finding some growing wild right at hand. Indeed, in most localities, it didn't seem to grow wild at all, but was carefully raised in a pot, like a flower. Where it did grow wild, it was always in some distant and inaccessible place. I should have suspected that this was simply blarney, and that our informants either wished to keep our profane hands off the shamrock or expected to get paid for going and getting us some, but for the fact that those who raised it always eagerly offered us a spray, and those who didn't usually disclaimed any exact knowledge of where it grew.
We bade the Clondalkin gardener and his helper good-bye at last, and walked on down to the village for a look at the remnant of the fort the Danes built here as their extreme western outpost against the wild Irish, and presently we fell in with an old woman, bent with rheumatism, hobbling painfully along, and she told us all about her ailment, and then as we passed a handsome house set back in a garden surrounded by a high wall, she pointed it out proudly as the residence of the parish priest. Then we thought it was time to be seeing about our car, and started down the street to find its owner, when we heard some one running after us. It was a man of about thirty, and his face, though not very clean, was beaming with friendliness.
"Is it a car your honour would be wantin'?" he asked.
"Yes," I said. "How did you know?"
"The man up at the church told me, sir. He said you'd be wishin' to drive to the station."
"Well, we do," I said. "It's too far to walk. Have you a car?"
