•28o Mr. Fork's Travels in the iaierior Parts if Africa. 



I have given this abridged account, becaufc it Is evident that fuch inventions are worthy 

 the attention of philofophers and economifts, even though in the firft applications they may 

 prove Icfs advantageous than their inventors may be difpofcd to think. It is fcarcely proba- 

 ble that this pradice in the large way, with an engine throwing upwards of 200 gallons (value 

 about 3I. los.) each minute, would be thought of or adopted, or that a fufficient ftore of the 

 materials would be kept in readinefs ; fince at this rate the expenditure for an hour would 

 demand a provifion to the amount of 210I. ftcrling, Bui in country places the procefs, or 

 fome variation of it, might be applied with fufficient profit in the refult ; more efpecially if 

 it be confidered that common fait or alum, or fuch faline matter as can be had and mixed with 

 the water, together with clay, chalk, or lime, ochreous earth or common mud, or eventhefo 

 laft without any fait, m^y anfwcr the purpofe of the lute with more or lefs efFeft; and ex- 

 tinguiih iin accidentjJ fire with much greater fpeed and certainty than clear water would do. 



Mr. Parle has circulated Propofals for publifhing by Subfcription (under the Patronage of 

 the African Affociation) his "Travels in the interior Parts of Africa, by Way of the River 

 Gambia, performed in the Years 1795, 1796, and 1797, by the Diredlion and at the Ex- 

 pence of that Affociation." The Work will form One handfome Volume Quarto, and is 

 expedled to be ready for delivery early in the enfuing Seafon. One Guinea is to be paid at 

 the time of fubfcribing, which it is expedcd will be the price of the Book; but as. the 

 charges are not at prefent afcertained, it is underftood that a further payment of Half-a- 

 Guinea wi![ be expefted, provided the Committee of the African Affociation fhall certify 

 th4t fuch demand is rcafonable, Subfcripiions are taken by G. Nicol, Bookfeller, Pall- 

 Mali. 



Proceedings of the Affociation for promoting the Difcovery of the interior Parts of Africa, 

 containing an Abftraft of Mr. Park's Account of his Travels and Difcoveries, abridged

The title-page renders it needlefs to repeat, that this book confifts of two diftindl works< 

 ^f the latter, whicjh adds no fmall portion to the well-acquired fame of its author, 1 have not 

 yet been able to fatisfy myfelf that any abridgment can be offered to the Public without 

 mutilations, which fuch a fubjeft cannot endure. The reader has already been prefented 

 with the concluding chapter in cur prefent number. The whole will be re-printed, to- 

 gether with the Maps, in Mr. Park's own work. Mr. Edwards's abftraft of Mr. Park's 

 Travels contains the following particulars :
