Llewellyn, of Wales. From a small eight-inch cylinder engine, employed by him for agri- 

 cultural purposes, this gentleman conducted a jet of steam for twenty minutes daily, through 

 an inch iron pipe, into a bed of rough stones, covered by a glazed frame ; a journal of the 

 temperature was kept, from which it appeared, first, that although steam was introduced 

 among the stones for only twenty minutes a day, the thermometer was raised from 51° to 

 68° in the first 24 hours ; second, that the temperature continued to rise for many hours 

 after the second application of steam, until the thermometer reached 108° ; third, that at 

 the end of 19 hours the heat of the frame diminished ; yet, fourth, that at the end of seventy 

 hours the temperature still was 69°. This is a conclusive answer to those who think that 

 masses of heated water, or heated porous materials, like rough stones, will become so reduced 

 in temperature by a few hours' witlidrawal of the prime heating power, as to endanger the 

 plants cultivated in houses thus warmed. The experiment continued to be successful, and 

 enabled pine-apples of the most perfect quality to ripen. A hint might be taken by many 

 manufacturers, to grow grapes and other fruits by the aid of what is now carelessly thrown 

 away. 



John W. Degrauw, Esq.'s annual address before the spirited Brooklyn Horticultiiral 

 Society has been printed in a neat pamphlet. It contains much matter of interest and for 

 thought. Such beautiful places as he desci-ibes in the vicinity of Brooklyn almost temx^t us 

 to leave our easy-chair. 



The Rev. L. Billings's Addeess before the Adams County Agricultural Society, Illinois, 

 comes to our table in neat and unpretending form, but is full of good thoughts well ex- 

 pressed. The report of the second annual fair, and the premiums, mark a most progressive 

 spirit, for which we are disposed to give Illinois a full meed of credit. 



Double Lilt of the Valley. — This beautiful novelty is beginning to spread a little among 

 us. It has been known for many years in this neighborhood, but has only of late been 

 procurable. It is one of the veri/ valuable additions to our sirring bloomers. 



Vinegar Plant. — We are indebted to William H. Williams, Esq., banker, of Pittsburg, 

 for a vinegar x^lant, which we have set to work. 



Mr. Glover, the naturalist of the Patent Ofiice, who was sent South, for the purpose of 

 investigating the nature and habits of the insects injurious and beneficial to vegetation, has 

 returned. The Commissioner of Patents expressed himself as highly gratified with the 

 repoi-t of Mr. G. in relation to the orange and scale or cocus insects, and the red bug and the 

 caterpillar, which are said to be very destructive to the cotton plant. 



Beautiful Picture. — Macaulay, who paints everything in strong colors, gives the following 

 picture in his new volume : " In the southwestern part of Kerry, on the rare days when the 

 sun shines out in all his glory, the landscape has a freshness and warmth of coloring seldom 

 found in our latitude. The myrtle loves the soil. The arbutus thrives better than ever on 

 the sunny shore of Calabria. The turf is of livelier hue than elsewhere ; the hills glow with 

 a richer pui-ple ; the varnish of the holly and ivy is more glossy ; and berries of a brighter 

 red peep through foliage of a brighter green. But during the greater part of the seven- 

 teenth century this paradise was as little known to the civilized world as Spitzbergen or 

 Greenland." 



Strawberries. An American in London. — The North American Review tells the following 

 good story : A countiyman of ours, of somewhat rude appearance, walking in the Strand 

 early in May saw his favorite disli of strawberries and cream blushing at liini from tlie 

 counter of a restauivant. Entering, he carelessly called for a bowl, to the marked surjirise 

 of several persons present, who knew the extravagance of the luxury, and rightly presumed 

 that the American was ignorant at what cost he was gratifying himself. He had not 

 finished his repast before the curious looks of the company suggested his mistake, and 

 aroused all his latent pride. " What is to pay ?" inquired he, as he laid down his dish, not 

 without a glowering side look at the wiseacres who waited for his chopfallen aspect when 

 the victualler's reply should fall upon his ear. "A guinea, sir." Tossing down the coin 

 from a not over full purse, and bridling up with an air of assumed indifference, " I '11 take 

 another!" was the American's only rejoinder. How many American travellers cover their 

 ignorance and pride at a similar expense !
