 Portland cement from a physico-chemical 

 standpoint.

 on experiments with materials which retard 

 the activity of Portland cement.

 trated account of the Edison Portland ce- 

 ment works, describing the machinery used.

 Cunningham of mortars and cements. 



SCIENTIFIC AMERICAN SUPPLEMENT 

 ■533 contains a resume of the cement in- 

 dustrv and gives some valuable formula. 



SCIENTIFIC AMERICAN SUPPLEMENT 

 1575 discusses the manufacture of hydraulic 

 cement. L. L. Stone is the author.

 1587 and 1588 contain an able paper by 

 Edwin C. Eckel on cement material and 

 industrv of the United States. 



SCIENTIFIC AMERICAN SUPPLEMENT 

 1586 contains a review of concrete mixing 

 machinery by William L. Larkin.

 tion of Portland cement for concrete blocks.

 for mortar and concrete, by Sanford E.

lowing spring. Before the plants have quite 

 grown together the space between them may 

 be utilized for planting other flowers. The 

 tritoma is very effective with the snowy pani- 

 cles of the hydrangeas ; so, too, is the ge- 

 ranium or the scarlet salvias. 



Another beautiful fall-blooming shrub is the 

 althea, and although this in time attains the 

 proportions of a small tree, it may, by prun- 

 ing, be kept to the dimensions of a shrub, and 

 when grown as a hedge and covered with its 

 wealth of double flowers is indeed a thing of 

 beauty. The double white Jeanne d'Arc, the 

 delicate blusli Grandiflora superba, the Alba 

 plena — white with crimson center. Rubra 

 plena — a double rose, are all satisfactory for 

 massing together, while the purple varieties do 

 best together or mi.xed with white alone. The 

 culture of altheas is simple, and they bloom 

 freely when very young. They should, how- 

 ever, be given some protection during winter, 

 and while young will be the better for wrap- 

 ping with straw or protecting with evergreen 

 boughs during severe weather. 



The fall blooming shrubs are more satis- 

 factory for conspicuous positions than those 

 w hich bloom in the spring, lovely as many 

 of those are. But the rhododendrons are orna- 

 mental in their foliage, and when in bloom are 

 so truly wonderful and gorgeous that they 

 shoidd be planted wherever there is a prospect 

 of their doing well — and one's means permit — 

 for the rhododendron is by no means a cheap 

 shrub, and who would possess a notable hedge 

 of them must reach deep into his pocketbook, 

 unless he is so fortunate as to live in those 

 favored localities where they may be had for 

 the digging. 



Unlike the generality of shrubs, the rhodo- 

 dendrons stand moving with much equanimity, 

 the roots forming a close ball of roots, which 

 seem little affected by being disturbed. The 

 plants require a deep, well drained position, 

 where they can be liberally supplied with 

 water, and when forming their buds for the 

 next season's growth they should be given 

 liquid manure twice a week. Unlike the hy- 

 drangea, they do not require prunning, but 

 may be allowed to make what growth they 

 will. They require protection in winter, 

 either of a frame and leaves or of evergreen 

 boughs. 



In July and August the edges of marshes 

 and wild spots are sweet with the odor of the 

 sweet pepper bush — Clethra ainifolia — whose 

 long spikes of white flowers are conspicuous 

 above the glossy foliage. This is one of the 

 best of our native shrubs and well worth culti- 

 vating for ornamental hedges. The bloom 

 much resembles certain spireas, and the odor 

 is much more agreeable. 



The crimson spirea — Anthony Waterer — is 

 magnificent for hedges, growing as it does in 

 a compact bush about three or four feet high 

 and blooming in dense panicles on the new 

 wood so that it lends itself -readily to shearing 

 in any desired shape. It blooms in June, but 

 by removing the flower panicles as they fade 

 it may be kept in bloom the entire summer, 

 and its crimson flowers are very attractive. I 

 know of nothing better for an ornamental 

 hedge. 



The weigelias are charming spring bloom- 

 ing shrubs for hedges, as they may be pruned 

 to any desired shape and will cover themselves 

 with lovely bloom for weeks at a time in early 

 spring, and certain varieties are ornamental 

 through the summer, as the Eva Rathke, which 

 blooms continuously, and the Rosa Nana Va- 

 riegata, whose foliage is beautifully variegated 

 with green, yellow and pink, and bears quanti- 

 ties of delicate pink flowers. One must not 

 overlook the Rosa rugosa, with its beautiful 

 foliage and striking single flowers of white 

 and of red. They make the most beautiful of 

 hedges, and the flowers are followed by bright
