HENDERSON'S HANDBOOK OF PLANTS 



EOS 



little white lead, just enough to give it the 

 appearance of thin milk. This we throw on 

 the outside of the glass with a syringe. It 

 costs only about twenty-five cents for every 

 thousand square feet. This shading is the 

 best we have ever used; it is just enough to 

 take the glare of sunlight off, without much 

 lessening the light ; and though it will hold 

 on tenaciously during the summer, is easily 

 rubbed off in fall. 



GAEDEN CULTURE OF THE HOSE. But little 

 need be said on this branch of the subject, all 

 that is wanted being a deep, rich soil, in an 

 unshaded position. For the dry climate of 

 the United States a class of Eoses should be 

 grown very different from those grown in 

 England. There the " Eemontants " or " Hy- 

 brid Perpetuals," in their humid atmosphere, 

 with few exceptions, flower nearly as freely as 

 the " Monthly " Eoses do here ; but with us 

 experience has shown that, after the first 

 bloom in June, no full crop of flowers is again 

 obtained, unless with the comparatively new 

 class known as the Hybrid Teas, of which 

 "La France, Dinsmore, and Duchess of 

 Edinburgh " are types ; BO that, when a con- 

 tinued bloom of Eoses is desired during the 

 entire summer and fall months, the class 

 known as monthly (embracing Tea, Bourbon, 

 Bengal, and Noisette) are the best. True, 

 these varieties are not usually hardy, unless 

 in that portion of the country where the ther- 

 mometer never gets 20 below the freezing 

 point; but they can be saved through the 

 winter in almost any section if pegged down and 

 covered up with five or six inches of leaves 

 or rough litter. This covering, however, 

 should not be done until quite hard frost 

 comes ; in New York about the first week in 

 December. If done sooner, there is danger, 

 if the season is mild (as it usually is here 

 until December 1st), that the shoots may be 

 smothered and decay by a top early covering. 

 This same rule we adopt in covering Grape 

 Vines, Clematis, Easpberries, Strawberries, 

 or, in fact, any other plant or shrub that we 

 believe to be benefited by winter protection, as 

 we have never yet seen injury done to half- 

 hardy plants by frost previous to that date. In 

 this matter of covering, the amateur in garden- 

 ing often errs, first from his anxiety to protect 

 his plants before there is danger in the fall ; 

 and next, in his enthusiasm in spring, he is 

 deceived by some warm day in March to un- 

 cover what is not safe until April. 



Rosaceae. A large natural order of herbs or 

 shrubs, very rarely trees, chiefly abundant in 

 temperate regions, extending into the Arctic 

 Zone, as well as ascending to the highest ele- 

 vations, and more sparingly dispersed within 

 the tropics. Bentham and Hooker, in the 

 " Genora Plantarum," have divided up this 

 extensive and important order into ten tribes, 

 several of which are regarded by some other 

 writers as distinct orders. Many beautiful 

 flowers are included in Rosacece, the Eose, of 

 course, taking the lead. The principal fruits 

 furnished are the Almond, Apricot, Apple, 

 Blackberry, Cherry, Peach, Pear, Plum, Quince, 

 Easpberry and Strawberry. Eose water is ob- 

 tained by distillation from the petals of R. 

 centifolia, Damascena, moschata, etc., as is also 

 the Attar of Eoses by maceration in oil of 

 Sesamum. The bark of Moquila utilis, the 



EOS 



Pottery-tree of the Amazon, contains such an 

 amount of silica that, when powdered and 

 mixed with clay, it is employed in making 

 pottery by the natives of Para. The order 

 contains about seventy genera, of which Cra- 

 tcegus, Prunus, Potentilla, Rosa, Rubus, and 

 Spircea are good examples, and one thousand 

 or more species.
