In a recent letter to Mrs. Lowell, Dr. Lampland also gives a glimpse into Percival’s life at Flagstaff; and though written to refresh her recollections she preferred to insert it as it stands.

“Fresh in memory and pleasant to recall are your many visits to Flagstaff and your activities at the Observatory, where you were designing and supervising architect, carrying through the additions to the director’s residence, the garage, and the new administration building. And I also remember your valued help to us in connection with the house in which we live and your telegram ‘Mr. Lowell gives benediction and sanction to plans. Proceed.’”

He then goes on to tell of Percival’s friends from both West and East, and continues:

“You remember he was an enthusiastic gardener and always had a garden here at the Observatory. He had great success with many flowers and I recall especially fine displays of hollyhocks, zinnias, and a considerable variety of bulbs. Gourds, squashes and pumpkins were also great favorites. You will remember one year the especially fine collection of gourds and that bumper crop of huge pumpkins, many prize specimens being sugar fed. At times Dr. Lowell could be seen in the short intervals he took for outdoor recreation, busy with his little camel’s hair brush pollenizing some of the flowers. And perhaps you will remember the little record book lying on the back veranda containing his observations of the daily growth of the diameter of the gourds, all measured carefully with little calipers. Then the frequent, almost daily, walks on the mesa. Certainly he knew all the surrounding country better than anyone here. He would refer to the different places such as Wolf Canyon, Amphitheatre Canyon, Indian Paint Brush Ridge, Holly Ravine, Mullein Patch, etc. In these walks he seemed to be constantly observing something new and of course trees, flowers, and wild life always interested him. Trees were an endless source of interest to him and he took many trips to more distant localities for these studies. Cedars or junipers seemed to be favorite subjects for study, though other varieties or kinds were not overlooked. An oak and an ash were named after him, new species that were discovered on the Observatory mesa and in Sycamore Canyon.

“At every season of the year he always found something in wild life to fascinate him, and you will remember his observations and notes of butterflies, birds, squirrels, rabbits, coyotes, deer and other inhabitants of the mesa. These friends must never be disturbed or harmed. But it was permissible to hunt with a camera! And he himself delighted with his kodak, photographing footprints, etc., and often attempting to get exposures of the creatures themselves. The Observatory grounds were a sanctuary for wild life.

“For many of us an interesting side of eminent personages is to know something about their activities, such for example as reading, outside of their professional occupations. In Dr. Lowell’s case you should find ample opportunity to treat a subject that will not admit of monotony. It would seem that practically every field of knowledge interested him. For the lighter reading as a relaxing and restful diversion you will remember the full bookshelves of detective stories, travel, exploration, etc. Accounts of adventure and discoveries, if well written, were welcome to his list of miscellaneous reading. The Latin classics were always near at hand, and widely and well had he read them, and much were they prized as friends in his later life.

“As you know, it is not easy for the observing astronomer to lead a strictly regular life in that the hours at the telescope often make it necessary to use, for the much needed rest, part of the daily hours usually given to work. His intense occupation with his research problems, however, was broken with great regularity for short intervals before lunch and dinner. These times of recreation were given to walks on the mesa or work in the garden. When night came, if he was not occupied at the telescope, he was generally to be found in his den. It was not always possible for him to lay aside his research problems at this time of the day, but he did have some wholesome views on the necessity of recreation and a necessary amount of leisure to prevent a person from falling into the habit of the ‘grind.’ To those who came to his den the picture of some difficult technical work near his chair, such as Tisserand’s Mechanique Celeste will be recalled, though he might at the time be occupied with reading of a lighter character. And occasionally during the evening he might be seen consulting certain difficult parts upon which he was pondering....

“The famous outing to the White Mountains was often the subject of much amusement at the dinner parties when Dr. Lowell and Judge Doe were both there. In later years that famous expedition seemed to be an inexhaustible source of fun—the voracious mosquitoes, the discomforts of a camp and beds under water, atrocious coffee, and so on!!

“And this reminds me of many dinner parties on Dr. Lowell’s and Judge Doe’s birthdays. These were jolly gatherings, and the brilliant repartee passing between Dr. Lowell and the Judge was a great delight to those who were present.

“Many things about the place often remind me of the intensely busy days before Dr. Lowell passed away. There were several excursions for his tree studies, to Sycamore Canyon, an arduous trip, and to other localities near Flagstaff for further studies of different species of junipers in their native habitat. The specimens were carefully sorted and packed for Professor Sargent of the Arnold Arboretum. Then I remember helping him plant many bulbs on the last two days before he was fatally stricken. The squills he planted at that time in the little bed under the oak tree near the entrance of the B. M. return every spring.”[34]
