I postpone till a future opportunity some farther remarks on the mutual 

 fecundation of plants, and on the divisions and subdivisions at present 

 adopted by botanists. Yours, &c. — J. C. K. Levant Lodge, 



To the seeds of 6'ucumis flexudsus sent, the seeds from Mr. Oliver's 

 mango cucumber (No. 1.) bear, in contortedness, colour, and in size, ex- 

 cept that they are shorter and broader, close resemblance. The seeds 

 (No. 2.) from the hybrid raised by Mr. Oliver, and described Vol. Vlll. 

 p. 611., bear an evident, but rather less close, resemblance to those of C. 

 flexuosus. On the seeds of the other kinds sent by J. C. K. it is not 

 necessary to speak. — J. D. 



Art. III. Queries and Answers. 



What Quantity of the under-named Kinds of Work slioidd a Workman 

 perform in a Day? — Sir, I venture to ask for an ai'ticle on the quantity of 

 work which a moderately good carpenter, mason, ploughman, country 

 workman in general, and labouring gardener ought to do in a day ? — I do 

 not mean fine work. How much sawing, for instance, or brick or rough 

 stone walling ? How much hedging, or ploughing, or ditching, or trenching, 

 or turnip-hoeing, or cutting of coppice wood ? How many sheep or cattle 

 one man can attend? How much a team of oxen, or horses, ought to do 

 in a day ? Or how much a gardener should dig ? Or how much garden 

 belonging to a villa one man ought to be able to keep in order through the 

 year? I am a young beginner, and am perfectly ignorant on these points, 

 as 1 am sure thousands are ; and I should be most delighted to find a list 

 of two or three pages, in your next number, estimating the quantity of all 

 sorts of such work as I might reasonably expect to have performed by a 

 fair workman. 



Movable Saw Mill. — The Duke of Athol, at Dunkeld, has established 

 a sort o? movable saiu mill in his woods, which is of very cheap and substantial 

 construction. Could you obtain the particulars, it would be extremely 

 useful in many other parts of the country. No doubt, a letter from you to 

 his grace, or to his manager in Scotland, would procure the necessary in- 

 formation, as every body must feel an anxious desire to forward your most 

 useful labours. — H. Johnson. 



Remarks contributive to an answer to one or two of Mr. Johnson's 

 queries, but still not supplying, even to one or two of them, either a direct 

 or full answer, will be found in Vol. IV. p. 447., Vol. V. p. 108. 12S.—J.D. 



Volumes in Dr. Lardner''s Cyclopcedia usefid to Gardeners. — Sir, Permit 

 me to recommend, through your Magazine, a ^ew books, which I have 

 found to contain more useful information on the subjects upon which they 

 treat, in a small compass, than I have been able to procure from more 

 voluminous reading; and which books or works would, in my younger 

 days, if I could then have obtained them, have been of inestimable value to 

 me. The books to which 1 allude are the scientific works in Dr. Lardner's 

 Cabinet Cyclopcedia, particularly the volumes on Mechanics, Hydrostatics 

 and Pneumatics, Chemistry, and Heat and its Practical Application ; 

 which may be procured, in separate volumes, at 6^. each, in cloth. The 

 volume on Chemistry, by M. Donovan, Esq., would answer the purpose of 

 Mr. Taylor (Vol. VIH. p. 733.) more effectually than any other book I 

 know; and would obviate the defect pointed out by Mr. Mallet (Vol. IX. 

 p. 122.), that English popular works on chemistry are defective in one 

 important point, viz., that of explaining the language which they speak. I 

 would likewise recommend to gardeners, whose local situation will admit, 

 to join mechanics' institutes, where very much information may be 

 obtained ; and, I believe, at an expense within the power of most young
