least in our ships of war, might appear surprising; for its ulility as (he Author remarks, cannot be doubted, without denying all the doctrines of pneumatics. For the necessity of adopting it in the navy, the great increase of the Dry Rot in our ships of war might be a reason sufficiently weighty. The increase of the disease in ships of that class, Mr. M. supposes, and we think his conjecture is just, to be occasioned in a great measure even by the improvements that have been made in the art of ship-building. Ships of war are now so tightly constructed as not to collect as heretofore much bilge water. When -bilge water was frequently collected, the necessity that existed of frequently pumping it off, gave occasion for the stagnant air of the hold to be pumped off with it; and our Author alleges that no instance can be adduced of any ship that collected much bilge water that was affected in any great degree with the dry rot, or was unhealthy to the crew.

The various means which Mr. M. suggests for preventing the introduction, and for arresting the progress of the Dry Rot, occupies so large a portion of the volume before us, that our limits will not allow us to do'that justice to those parts of the work to which their obvious utility lays claim. The advantages of charring timber, where that process is admissible, the impregnation of it with oleaginous and resinous matter, with many of the neutral salts, and with such of the metallic oxyds as readily unite with the juices of the plant, the extraction of the native juices, the immersion of the timber in water, and in peat-moss, the felling of it at a proper time, and the seasoning of it in a proper manner, are all treated in a manner which proves the writer to be well acquainted with his subject, and which cannot fail to furnish the reader, who feels interested in the subject, with much satisfactory information and practical aid. Passing over this portion of the work, we proceed to notice what the Author terms the Appendix, and which occupies nearly one half of the volume.

The Author's object, in this part, is not less important than, in the preceding. He endeavours to promote the cultivation of what, in the first portion, he has been anxious to preserve; and, while he shews from the increase of our population, and commerce, as well as from the increase of the causes of the decay of timber, that the demand for timber has been continually increasing, he proves from historic documents, as well as from tradition, that the quantity produced in Great Britain has been most unwisely suffered to diminish, almost in an inverse ratio to the demand. The annual value of timber cut down in the United Kingdom, Mr M. states, to amount to about three millions of pounds sterling; and, according to the Custom House Returns, the annual value of timber imported, exceeds the other amount; yet, though the consumption is such as to cause the balance of trade with certain countries to be considerably against us, no efforts have been made to raise a sufficiency of native supply. Many parts of the kingdom, on the contrary, which have been cleared of their native woods, have been only given up to barrenness ; and many parts of Scotland as well as of England, which •were known to bear, or which still retain the names of forest land, cannot now boast of a tree or a shrub, uor are they worth the expence of tillage. Yet our Author proves by various references, that in all climates, from the equator to the arctic regions, timber trees may be produced, and there appears no reason to doubt that wood will grow on any soil, from the sea beach to the mountain top, on the almost rock, on the quagmire, under the glowing rays of a vertical sun, till we approach the regions of ice and snow. The selection of the trees for the various soils and situations, appears to be the principal object which the cultivator has to study. The opportunity of planting in Great Britain appears to be as ample as can be desired. About twenty millions of acres of land are lying in a state of waste. Since the reign of Queen Anne, 3,046 acts of parliament have indeed been passed, by which 6,450,104 acres have been allowed to be enclosed, and put into a state of cultivation. Of these, a large proportion, however, are still only fit for bearing timber trees; and for the purpose of planting them, there is unquestionably a supply of people to be found who would be content to be employed at very moderate wages.

The inducements which the Author holds out for planting on inferior lands, are rational and powerful, and instances are adduced where land not worth a shilling an acre per annum, before it was planted, had produced an average profit, from the time of planting, of ten and twelve pounds a year, per acre, and in some cases even more. 'However extravagant it may appear,

* yet facts sufficiently prove, that the value of the fee simple, 'even of good land, bears but a diminutive proportion to that of

* wood of fifty or sixty years growth, or even less than half that

* time, after planting on the most sterile soil.' i' The suggestions offered respecting the propagation of trees,

the choice of soil, and the mode of training, may be read with advantage by country gentlemen who are disposed to embellish, or to improve their lands. The sectiou respecting the forest laws contains much curious matter; and that which concludes the work, on the policy of building ships in India, is of peculiar and immediate national interest.

Uninviting as the title and the topics may appear, and limited «s the interest of the general subjects may be, we do not hesitate to assert that the collateral materials with which the volume abounds, will be found to afford an unexpected gratification even to general readers who may be induced to peruse it.

The Author has accomplished his task with indefatigable industry, and with much ingenuity and intelligence. The principles on which he reasons as to the causes and preventives of the decay of timber, appear to be perspicuous and sound, and his aim in endeavouring to rescue the treatment of the subject from the hands of the ignorant or designing empiric is highly worthy of praise.

Art. XIII. A Letter on the Principles of the Christian Faith. Written by Hannah Sinclair, Eldest Daughter of the Right Hon. Sir John Sinclair, Bart, who died on the 22d of May, 1818. 8vo. pp. '25. Price Is. Gd. London, 1818.

\ \7 l'; are very glad (hat this " Letter" has not been confined to * TM a private circulation : it is adapted to be extensively useful. It will interest on account of the circumstances under which it was written; it has, however, the merit of not only being dictated by an affectionate spirit, but of conveying, with peculiar clearness, simplicity, and accuracy, the principles of what we denominate evangelical religion. The Apostle would not have women speak in the churches; he did not suffer them to teach in public; but as parlour-instructors, as private monitors, there are none equal to mothers and sisters, inasmuch as their counsels, imparted in the tone of persuasion, find a readier access to the heart. Besides which, truth in the female mind, exists, perhaps, in more uniform and intimate combination with the feelings, than in the minds of men in general; and religious truth more especially, •when intelligently embraced, occupies more habitually the affections of women as a practical reality; it is to them not only the subject of belief, but a source of real delight. Where this is the case, there will be the freshness of life in the representation given of its doctrines; the style of address will be regulated by the " law of kindness;" and it will have the charm of an earnestness not easily to be withstood.

The Writer of this letter was in the habit of instructing her younger brothers and sisters in the knowledge of religion; it was her great delight to be thus occupied. The wish expressed by one of her sisters, that she should put down in writing, the substance of some of the conversations which had passed between them, was the occasion of this letter, which, it is almost needless to state, was never intended for the public eye. The death of this amiable and exemplary young lady, only seven months after the date of the letter, has set upon the production, however, the additional value of a memorial, which those who knew her, will doubtless be peculiarly happy to possess. In recommending it to

our readers, we need only transcribe a short passage as i' cimen.

Art. XIV. The Character and Success of Barnabas; or the Connexion between eminent Piety and distinguished Usefulness: A Scrmen, preached on Acts xi. 24. By Thomas Durant, 8vo. pp. 4-8. Price Is. 6d. London. 1818.

1 F to serve and enjoy God were the grand purposes for which *- man was brought into existence, ami for which lie holds his present rank in the scale of being, (and to what other purposes consistent with the character of God, can wc ascribe his being and intellectual power r) it must be obvious to every reflecting person, that the world has not yet answered the end of its creation. A man does not purchase a house, or an estate, to allow it to remain unoccupied; nor does a master hire a servant to waste his property and disobey his orders. It is impossible to look at the history of the past, or to contemplate the present, and suppose for a moment that God has no higher euds to answer by this world, than we have already witnessed. Is the wealth of the world employed in the service of God? Are piety and obedience to the Divine law the leading character of its inhabitants? Are men generally employed in doing justice, loving mercy, and walking humbly with God? To these questions it is unnecessary to wait for an answer. Is not the reverse of all this the case? How just the description of the Apostle, " All that is in the world, "is the lust of the flesh, the lust of the eye, and the pride of life!" Is it reasonable to suppose that things are always to remain in this state? Are iniquity and irreligion always to prevail? Are the authority, the laws, and the goodness of God, to be always trampled in the dust?

There are only two principles on which tlie supposition is admissible; and these principles are as repugnant to reason as they are to the doctrines of Revelation. There must exist either power or inclination in the Almighty to make things otherwise. Power lie cannot want: He who lias all power in Heaven and on Earth, and who raised up the fishermen of Galilee, gave them the qualifications which they possessed, sent them forth as his messengers, and blessed their labours to the conversion of the nations, cannot be at a loss for means to accomplish his purposes. Paganism and Popery were once in as full possession of the high places of our country, as they now are of Africa and Spain. Both were successively attacked by the arms of Divine truth,and these heavenly weapons have lost none of their temper, but are as mighty, through God, to the pulling down of strong holds and every thing that exalteth itself against the truth, as ever.

To say that God wants inclination to make his creatures good aod happy, is blasphemy. "He hath no pleasure in" the misery or "the death of the sinner." He delighteth in mercy..
