GLAZING WITHOUT LAPPING. 



BY PETER HENDERSON. 



Some one in a recent number of the Monthly 

 advises to glaze without lapping the glass. Be- 

 fore any one acts on that advice, he had best test 

 its soundness by experimenting a little. When 

 rebuilding our greenhouses here in 1878, I gave 

 the " no lap" plan a careful trial by glazing in 

 that way a section of a twenty-foot house, having 

 an angle of about thirty-five degrees. We first 

 tried it by showering over the glass with a hose, 

 and found that it leaked like a sieve. Not quite 

 satisfied with the hose test, we waited until a 

 heavjf rain fell, which showed nearly the same 

 result; the roof leaked on that part where the 

 glass had not been lapped so as to be de:<tructive 

 to anything growing underneavh. Were it pos 

 sible that the glass could be cut so that when 

 butted together the junction would be per- 

 fect, then that plan would certainly be the best; 

 but that would be next to impossible. In the 

 trial we made the glass was selected with the 

 greatest care, yet in many places the point of a 

 penknife could be run between the panes where 

 they were' joined together; consequently that 

 even at the steep angle we used it on, the leak- 

 age was such as to show that the practice was a 

 bad one in any place where water falls on the 

 greenhouse roof. 



We find no better plan in glazing than that 

 now almost universally in use of bedding the 

 glass in a thin layer of putty and tacking down 

 tight with good-sized glazier's points, using no 

 putty on the top, but instead, painting thickly 

 with white lead. The laps should never exceed 

 one quarter of an inch, and often an eighth of 

 an inch is deemed sufficient. 



CYDONIA JAPONICA— THE COMING 

 HEDGE PLANT. 



BY. WM. WEBSTER, ROCHESTER, N. Y. 



One of the problems which have long engaged 

 the attention of horticulturists is that of a suit- 

 able plant for both ornamental and useful 

 hedges; one that shall be characterized by its 

 easy growth, strength, and durability, and that 

 is capable of withstanding not only the attacks 

 of animals but of injurious insects also. Some 

 of the different species of Coniferae make beauti- 

 ful ornamental hedges, but practically are of little 

 use when exposed to the attacks of animals. 

 While some among deciduous trees such as the 



Hawthorn and Osage Orange, though strong and 

 hardy enough to resist the onslaught of animals 

 frequently succumb to the more silent attacks of 

 insects by which they often become infested. 

 Hence it needs no prophet to foretell that the 

 plant which combines in the greatest degree the 

 different characteristics I have mentioned must 

 be the favored one. 



In looking over the nursery stock on the 

 grounds of Mr. James Craib of this city in com- 

 pany with that gentleman, a short time since, 

 my attention was attracted to a fine lot of seed- 

 ling Cydonia Japonica plants, and on remarking 

 upon their fine healthy appearance and uniform- 

 ity of growth, Mr. C. informed me that he was 

 raising them for hedge plants, and it was a sub- 

 ject that he had been experimenting on for some 

 time, and to show how well he had succeeded in- 

 vited me to go with him to a distant part of the 

 grounds and examine a specimen hedge of seed- 

 lings. This hedge appeared to be about 150 feet 

 long. The plants which had been transplanted 

 were four years old from the seed ; had been 

 trimmed as needed, are now about three feet in 

 height and the same in width. The plants are 

 generally of uniform size, of robust habit and 

 are now bearing a large quantity of fruit, of 

 various shades of color; some are of a light 

 green, others tinted like a ripe Apricot while 

 not a few resemble Seek el pears. The foliage is 

 dark green and the hedge as compact as any 

 one could desire, and not a scale or bug of any 

 kind to be seen on it. Here I remarked you 

 have a "bonanza," and one that requires work- 

 ing and that ought to be made public, for this is 

 the kind of hedge that we have been waiting for 

 so long. 



Perhaps on reading this some may smile 

 and say what is there new about a Cydonia 

 Pyrus Japonica hedge. I answer true to a cer- 

 tain extent there is not, for I have been familiar 

 with the plant ever since I can remember any- 

 thing about plants. Neither is there anything 

 new about "electricity," except in its scientific 

 application to the uses of the present time ; this 

 is an age of progress and none of us are too old 

 to learn. I have seen much larger hedges of Cy- 

 donia than this one, but they were very much 

 older. Mr. Charlton a neighbor of Mr. C. has a 

 magnificent one which in its season is a perfect 

 blaze of blossoms, and what has kept this plant 

 from being more generally adopted has been the 

 supposed difficulty in raising the plants. What.is 

 claimed for this seedling hedge, and which to
