If the pergola itself is built during the summer, you can sit under it, and by going over your list and colour scheme locate each rose finally before its arrival. By the way, until the climbers are well started you may safely alternate them with vines of the white panicled clematis, that will be in bloom in August and can be easily kept from clutching its rose neighbours!
By and by, when you have planted your roses, tucked them in their winter covers, and can sit down with a calm mind, I will lend you three precious rose books of mine. These are Dean Hole's Book about Roses, for both the wit and wisdom o't; The Amateur Gardener's Rose Book, rescued from the German by John Weathers, F.R.H.S., for its common sense, well-arranged list of roses, and beautiful coloured plates, and H. B. Ellwanger's little treatise on The Rose, a competent chronology of the flower queen up to 1901, written concisely and from the American standpoint. If I should send them now, you would be so bewildered by the enumeration of varieties, many unsuited to this climate, intoxicated by the descriptions of Rose-garden possibilities, and carried away by the literary and horticultural enthusiasm of the one-time master of the Deanery Garden, Rochester, that, like the child turned loose in the toy shop, you would lose the power of choosing.
Lavinia Cortright lost nearly a year in beginning her rosary, owing to a similar condition of mind, and Evan and I long ago decided that when we read we cannot work, and vice versa, so when the Garden of Outdoors is abed and asleep each year, we enter the Garden of Books with fresh delight.
Have you a man with quick wit and a straight eye to be the spade hand during the Garden Vacation? If not, make haste to find him, for, as you have had Barney for five years, he is probably too set in his ways to work at innovations cheerfully!
