H. J. Campbell & James Sproule were managers of Sherwood Hall Nursery Co. in 1893. Their catalog does not include 'Coquito'. The nursery was subsequently renamed Sunset Seed & Plant Co. which reportedly introduced Burbank's Seedling Rose M. 19,925, but I can't find it, either.

I was searching for info on James Sproule, hoping to find a catalog or list showing the introduction of 'Coquito'. Instead I found this:

James Sproule
A few days ago we were pleased to receive a letter from James Sproule, whom many of our readers will recall in connection with the trade in California. Mr. Sproule will also be remembered as the author of that phrase to which he gave expression in September, 1898, when he said: "This seems to be a season of growth depression the world over." We made some comment upon this at the time, as follows:

"This seems to be a season of growth depression the world over," says James Sproule, the San Francisco seedsman, "Growth depression" is a good phrase. We have needed this; it appeals to him who grows and the seedsman who contracts; it is also full of meaning. The coining of such a fitting expression is a recompense these troublesome times. And why should it not prove useful to the flower grower? For example: It shrinks the roses to half a crop at Christmas; it blights big batches of Harrisii; carnations won't open, or prematurely go to sleep; Beauties, under its baneful influence, abort, with insignificant stems and poor foliage. Need we illustrate further? "Growth depression" explains so many things, it must have come to stay.

Mr. Sproule is at present located in Yukon Territory, where he is engaged "in a try for gold more directly than through the medium of flower specialization."
