WINDOW GARPEN ATTRACTIONS

lent plant for the window box, as its graceful habit of 

 growth and brilliant flowers are very effective ; no manure 

 should be added to the soil for nasturtiums; Petunia, a 

 plant which produces a succession of bright-colored, 

 broad, trumpet-shaped flowers which give brilliancy to 

 any collection ; Snapdragon, a rather slow plant to bloom, 

 but one that is attractive while growing and makes a good 

 background for the other plants of the collection and is 

 very brilliant and showy when it does bloom ; Sweet Allys- 

 sum, a low-growing, spreading plant, with small, white, 

 sweet-scented flowers, produced in abundance; Verbena, 

 a trailer which covers two to six square feet and is an 

 abundant and persistent bloomer ; Zinnia, a strong, rather 

 coarse-growing plant, but very hardy and a persistent 

 bloomer. 



There are many other plants which are suitable for 

 window-box use. With any combination, certain foliage 

 plants should be used to furnish a sufficient filler or 

 background for the flowers. Among these asparagus, 

 red and green dracena, English ivy, sword fern, Whitmani 

 fern, pandanus, vinca, and wandering Jew are most 

 adaptable. 



The great range of available plants makes it impossible 

 to indicate exactly what the arrangement and combina- 

 tions should be, but the following examples are sug- 

 gested :

A FORESTRY CONFERENCE 



A FORESTRY conference held at Pittsburgh, June 21, 

 ^^ 22 and 23, was well attended by members of the 

 American Forestry Association, Pennsylvania State For- 

 estry Association, Canadian Forestry Association and 

 other organizations interested in forest conservation. 

 Three full and profitable days were spent in hearing 

 addresses, in viewing municipal plantings, nurseries and 

 examining forested lands in various sections of the state 

 near Pittsburgh. Dr. Henry S. Drinker, president of the 

 Pennsylvania Forestry Association and a director of the 

 American Forestry Association, presided at the sessions. 

 Owing to illness Mr. Charles Lathrop Pack, president

 conservation to be read. 



A GIANT CACTUS 

 By Stanley F. Wilson 



THIS giant cactus (Cereus giganteus) was found at an- 

 elevation of 3600 feet twenty-five miles northeast of 

 Tucson at the border of the Santa Catalina Divi- 

 sion of the Coronado National Forest. 



Its height is forty-five feet; its diameter breast-high, 

 twentv-six inches. There are more than fifty branches. 



ARIZON.^'S GIANT CACTUS 

 This great plant, weighing five tons, is forty-five feet high and has a diameter 

 of twenty-six inches. 



It is estimated that the weight of the plant is more than 

 five tons. Its age is unknown, but must be very great. 

 The dots are woodpecker holes. These birds delight in 

 the giant cactus. It furnishes a fortified residence for 

 birds of many species. 



Most people see only the desert country in travelling 

 through Arizona. This is because the railroads follow the 

 lower levels. How many people would believe that on the 

 summit of the Catalina Mountains, only nine miles from 

 this cactus, are to be found giant firs and pines, Alpine 

 wild flowers, a well-stocked trout stream, an ideal summer 

 climate, and a rapidly growing summer colony where 

 people take refuge from the heat of the desert ?
