UNPATENTED PLANT PROTECTORS. 

 I remember observing some time ago in your Journal an 

 announcement that the gentleman who has taken out a patent 

 for putting a groove in a brick, in order that it may support a 

 sheet of glaes, purposed to proceed against another gentleman 

 who had imagined himBelf at liberty to put a groove in a piece 

 of wood for the same purpose. If this is the case, the patent 

 laws may well need revision, and there will be many who will 

 agree with Sir Koundell Palmer in thinking they do more harm 

 in obstructing the progress of science than good in rewarding 

 merit. Doubtless it has not escaped the recollection of all your 

 readers that a patent was given some years ago for attaching 

 a hinge — no very great novelty, one would thinjc — to a ground 

 vinery, when the vinery itself, which was indeed a serviceable 

 and new thing, had been protected by no patent, which is much 

 the Bame as if one man were to invent a flying machine, and 

 another were to take out a patent for it because he had thought 

 of painting it sky blue. 



The patented glass protectors I have tried, and cannot say 

 much in their favour. UnleBs three or four bricks are piled 

 upon one another to a height which is precarious, there is not 

 room in them for Strawberries, much less for Vines. They are 

 of most service in winter for protecting plants for salad, whioh 

 are not so tall. But they are apt to break the glass. Mine 

 were held together by running a strong lath through the hollow 

 bricks, which prevented their ever being knocked down ; but 

 the inevitable upheaval and sinking of the soil under the frosts 

 and thaws of winter brought the rude edge of the brick into 

 such harsh contact with the brittle glass, that much damage 

 was done, and I am inclined to think that the gentleman who 

 excogitated a groove of wood was the more worthy inventor of 

 the two. The bricks are also costly to buy and cumbersome 

 to have sent by rail. 



However, why not do without wooden support or brick sup- 

 port, escape all danger of infringing patent laws, and have 

 your protector of glass only ? Nothing easier. Drive some 

 stout stakes into the ground along your row of Strawberries or 

 Peas, or whatever you care to protect. To the top of these 

 stakes fasten a lath, against which your glass will lean, set up 

 on end like the cards with which a child begins to build his 

 card house. Your lath will be 12 or 18 inches from the ground. 

 As you wish your glass to cover much ground or little, a broad 

 plant or a tall, present an obtuse or an acute angle. Viewed 

 endwise, your structure will present the appearance of a pointed 

 tent ; sideways, of a long glass ridge. The glass should not 

 be less than 20 by 12 ; 21-oz. will be the most durable, and 

 here the third or fourth quality will do well enough. A frail 

 structure, if you please, but thoroughly transparent, all glass ; 

 and the wind will have no power to blow it down if you run 

 some strong string outride it from end to end, fastened to the 

 end posts, and tightened from time to time as it slackens with 

 the weather. Ventilation may be given ad libitum by slipping 

 the panes over one another. 



I will undertake to say that with due ventilation Strawberries 

 of higher flavour may be grown in tbis way than out of doors, 

 and they ripen ten days or a fortnight earlier. Peas certainly 

 will rioen a fortnight earlier. When they reach the top of 

 their " house" the southern side may be taken away, and the 

 Peas allowed to ramble on the ground ; or if sticks are required, 

 glass may be set perpendicularly on either side against the 

 sticks, secured as before with a cord, and it will afford con- 

 siderable protection, but the other plan brings the first Peas. 

 I ran a ridge along an Asparagus bed, but there it did not make 

 any perceptible difference. One advantage of the plan is, that 

 when your glass houses are no longer wanted they are put in a 

 box and out of sight, instead of lying about cumbering the 

 ground. 



Will you put my plan in practice and give mo the patent of 

 your approval? — Wteside. 



Gilia liniflora. — In a recent number of your Journal I find 

 a report of an exhibition of plants at Paris, at which Messrs. 

 Vilmorin, Andrieux, & Co., are stated to have shown some new 



Underground Flowers.— A vegetable curiosity, met with 

 in New Zealand, has been described by Mr. Taylor, says the 

 Scientific Beview, in whose honour it has been named Daoty- 

 lanthus Taylori. He describes the plant as a parasite, wbich 

 attaches itself to the roots, and not like others to the branches,
