before purchasing plants in the spring. It may also be noted 

 that as yet this sport has not been named, so that it cannot be 

 more definitely spoken of than " Burton's sport from American 

 Beauty." 



Among indoor Roses in general this is one of the critical 

 periods of the year, from the extreme liability of some varie- 

 ties to contract mildew. Proper attention to watering, ventila- 

 tion and heating, with applications of sulphur, removes this 

 trouble readily. Probably the best method of applying the sul- 

 phur is by means of a bellows, after which the house should 

 remain closed for a time in order to allow the fumes to 

 operate on the fungus, keeping in mind the fact that if the 

 temperature is allowed to run up above ninety degrees there 

 is much risk of injuring the Roses. 



The night temperature of a rose-house is rather difficult to 

 regulate at this season without very careful firing. Fifty-eight 

 to sixty degrees is the most satisfactory temperature for a ma- 

 jority of the varieties in general use, while special varieties 

 may need either higher or lower than this average. 



Difficulty is usually experienced in successfully growing a 

 considerable number of different varieties in one house, but I 

 recently saw a house in which were Papa Gontier, Catherine 

 Mermet, Bride, Niphetos, Madame Hoste, Perle des Jardins, 

 W. F. Bennett, Souvenir of Wootton, Madame Cusin and 

 Madame de Watteville, and the grower informed me that the 

 only varieties he had any trouble with were Bennett and 

 Wootton ; at the time I saw them even these were in nice 

 condition. 



The method of staking Roses, to which reference has sev- 

 eral times been made in Garden and Forest, continues to 

 grow in favor — that is, the plan of using galvanized steel 

 wire rods in place of wooden stakes. These are kept up- 

 right by securing them at the top to a longitudinal wire at- 

 tached to the roof of the house. The galvanized steel wire is 

 very durable, does not require any painting, and forms the 

 neatest possible support for the plants. It has in addition the 

 merit of cleanliness, for it does not harbor vermin, as is fre- 

 quently the case with wooden stakes. The canes that have 

 frequently been used for this purpose form admirable hiding- 

 places for the Snout-beetle (Aramigus Fullerii), and this pest 

 is not slow in discovering any such cover. Fumigating or 

 vaporizing with tobacco extract will be found necessary from 

 time to time, vaporizing being tlie better method when prop- 

 erly applied, and less liable to injure the color of the flowers ; 

 but even this will affect the color if given too freely.

Lilies in Autumn. 

 TV/r ANY of the more valuable horticultural experiences are 

 •'■•-*• the results of accident, and not infrequently a little mis- 

 fortune as well. Last spring one of our seedsmen had a num- 

 ber of cases of assorted Lilies left over from spring sales. 

 After their journey from Japan in November of the previous 

 year, and having been kept perfectly dry until the middle of 

 May, the prospect of flowers from these bulbs was poor in- 

 deed. In hopes of saving something out of them, we planted 

 the lot about May 20th. To our surprise, nearly all of them 

 came up and made a vigorous struggle for life. The result 

 was that this morning (October loth) we have gathered from 

 a bed of L. Tigrinum splendens as fine spikes as ever were cut 

 in July. The plants of L. speciosum did nearly as well, but 

 their Howers were over last week, excepting L. speciosum 

 Prsecox, which are in bloom, although the flowers are consid- 

 erably damaged by the storm. L. longiflorum bloomed well, 

 but were all gone a month ago. The plants of L. auratum be- 

 haved as they always do ; some came up quickly, and flowered 

 in August, and there have been flowers in the row every day 

 since, while some are just coming up. These we shall pot for 

 the greenhouse if there are enough to make it pay. 



This experience has taught us that the season of Lilies can 

 be kept up until after a hard frost with but little trouble, and 

 add greatly to the display of autumn flowers. From the show 

 these Tiger-lilies are making, it is evident they should not be 

 allowed to bloom at any other season, as their deep, rich 

 orange-crimson flowers are now in harmony with all their sur- 

 roundings. For autumn flowers the bulbs should be taken 

 up in November, packed away in dry sand or sphagnum-moss, 

 and stored in some dry cool place until about May 15th. The 

 low price of the bulbs of Ihe L. tigrinum should make them 

 popular autumn flowers, when they can be had with so little 

 trouble and expense.

Anthracnose of the Pear. — There is a considerable decay of 

 the maturing pears due to an anthracnose. This rot of the 



fruit is quite different from any other of the decays met with 

 under similar conditions, and seems to have escaped identifi- 

 cation. The fruit may be attacked at only one place, which 

 spot soon turns Ijrown and becomes sunken, as if it had been 

 pressed upon with the end of the thumb. A little later the 

 surface of the sunken place becomes covered with dark pim- 

 ples, which are broad, instead of sharp-pointed, and finally be- 

 come almost black. These pimples are the places where the 

 spores are produced in great numbers upon the tips of pro- 

 jecting threads. The darkness of the pimples is due to the 

 multitude of small black bristles which project in all direc- 

 tions from the centre of the mass of spore-bearing tips. Each 

 pimple, in other words, is like a minute chestnut-bur, with 

 microscopic spores borne between the spines. 



A similar disease has been common upon the tomato during 

 the season now closing. This trouble of the pear may be met 

 with in the market, where it causes ruin to a fruit in a few days. 

 Pears left upon the ground also exhibit the same, and become 

 a means of propagating the anthracnose.

The Future of the Fair-grounds. 

 To the Editor of Garden and Forest : 



Sir, — What will eventually be the fate of the World's Fair- 

 grounds at Chicago ? All the buildings, except, possibly, one, 

 will, of course, be removed ; but a great deal of labor and of 

 art has been bestowed upon the site as such, and how much 

 of this will prove to have been expended for a temporary pur- 

 pose only ? 



The northerly portion of the grounds had been laid out as a 

 park before the Fair was proposed. This portion has neces- 

 sarily been somewhat altered, but can easily be restored to a 

 condition equal, or superior, to its former one. If Mr. At- 

 wood's beautiful Art Gallery is preserved, as its fire-proof walls 

 will permit, necessitating only the substitution of marble or 

 terra-cotta for the present external covering of "staff," it will 

 be a priceless addition to this part of Jackson Park. More- 

 over, this park is intimately connected with the new lagoon 

 and its charmingly planted island, where the Japanese temple 

 and garden will be permanently maintained ; and it will not 

 be difficult to transform the areas around the lagoon, now 

 covered by great buildings, into harmony with its shores and 

 with the regions further to the north. 



But beyond the lagoon to the southward the grounds have 

 been disposed in a very different way. Here the scheme is a 

 formal one, and verdure does not enter into it at all. Here 

 there is not only the fine, wide, curving esplanade along the 

 lake-side, but the great rectangular basin, running in at right 

 angles to the lake-shore, and branching out in front of the 

 plaza into straight wide canals. At present the effect of the 

 grounds, as a whole, is as harmonious as it is magnificent, 

 terraces like those which border the basin and canals being 

 carried for a space along the sides of the lagoon, where one 

 of the canals debouches, thus intimately uniting, in a way 

 which satisfies both the mind and the eye, the naturalistic and 

 the formal portions of the great design. 



But what is to be done with the iormal portions after the 

 Fair is over ? Must tlie basin and canals be destroyed, and, if 

 not, how can they be fitted into any artistic gardening scheme .? 

 An interesting answer to this question was recently given by a 

 writer in the Boston Herald. "On the terraces wliicli border 

 the basin and canals," he says, "and on the wide level ex- 

 panses left by the removal of the buildings ... it would be 

 possible to lay out a formal garden on a great scale, elaborate 

 in design and with rich and brilliant ei3'ects in the harmo- 

 niously blending and contrasting colors presented by extensive 

 flower-beds and formal shrubberies, studied as carefully with 

 reference to coloristic impression as any woven orembroidered 

 fabric in its conception. Such a treatment of that portion of 

 Jackson Park would be a revelation in the field of formal gar- 

 dening, and its success, which could not fail to be ^"^reat, would 

 go far toward creating a distaste for the atrociously bad art of 

 so much of the prevalent methods in flower-bedding effects, 

 repellant in both their awkwardness of design and their dis- 

 cordant colorings." 



This interesting suggestion would, we think, offer an ideal 

 solution of the problem but for one important fact. There is 

 another name for formal gardening ; it is also called archi- 

 tectural gardening, and in this name we find a hint of the 

 obstacle which lies in the way of the easy realization of the 

 proposed scheme. An architectural garden implies the pres- 

 ence of a work of architecture. A formal garden is the
