A correspondent asks how to find the height of trees, etc. The following plan is the ne plus ultra of simplicity: Cut a triangular board to an angle of 45°; support the base of it on a stick at the height of your eye, placing a common level along its base, to keep it horizontal Then walk away from the tree, taking the whole apparatus with you, till your eye, looking up the sloping side, strikes the topmost twig. The distance from your stick to the tree's base, measured along the ground, plus the height of your eye from the ground, is the total height of the tree. Crux.

P. 8. - A clever fellow will see how to make a plummet and line do instead of a level.

Mr. Editor. - Dear Sir: - Enclosed I send you a small specimen of an extraordinay seedling Verbena - the size of the individual flowers and the thryse-like racemes upon which they are borne, surpass all that ever came under my notice. The color is a great improvement upon "Geant Des Batailles," with a rich, dark velvety crimson eye; the foliage is also remarkably fine, and sinuate to a remarkable degree. (Very fine. - Ed).

It has been asserted that it was impossible to fertilize the Verbena. I have thought differently, and was determined to make a trial; the only way open to my mind to fully prove the matter was to be fully convinced of the possibility or impossibility of effecting the crop by producing a variety dissimilar to anything yet produced. Nine-tenths of the Verbenas imported from England have conspicuous while or femon-colored eyes. My idea was to produce a variety with a dark eye. How far I have succeeded the specimen will show.

The enclosed pansy blooms are seedlings - Tree, American Born Citizen. I have heard much of your Philadelphia pansies; if you have any finer than these, please inform me. (None better. - Ed.) I am yours truly and respectfully, Daniel Barker, West Maiden, Conn, Pray, my dear Mr. Horticulturist, what led the learned body to which you belong to change Thuya to Thuja 7 If a change was demanded, why did they use; rather than the more obvious i? Does the change involve a change of sound 1 I ask because I heard lately from a gardener - teacher of gardeners - that "We call the plant Thuja; (the gardener was wrong. - Ed.) he giving a consonant sound to; as in jam. Is this true for all we? I do not know, for I am familiar with the name only as written. Arbor Vitae in the only name I hear spoken; but euphony forbid that we amateurs who like to show off our learning occasionally, should be forced to give up a sweet sound for a harsh one. The French pronounce the word only as I hope we ought; although they have, as we have, two modes of spelling, Thuya and Thuia; this latter being an exact transcript of the Greek name of the sweet-smelling wood used for burnt sacrifices, supposed to be one of the genus Thuja.

Be so kind as to enlighten " one of your parishioners".
